For the first time, scientists have developed artificial nucleotides, the building blocks of DNA, with several additional properties in the laboratory.
Base editing, which Lius team developed in 2016, is a gene editing technique that directly converts an individual DNA base pair into a different base pair. Prime editing, which Lius group pioneered three years later, can make insertions, deletions, and substitutions up to hundreds of base pairs long in the genome.
Aleksandra Radenovic, head of the Laboratory of Nanoscale Biology in the School of Engineering, has worked for years to improve nanopore technology, which involves passing a molecule like DNA through a tiny pore in a membrane to measure an ionic current.
What is special about these synthetically designed elements is that they show remarkable specificity to the target cell type they were designed for," said Ryan Tewhey, an associate professor at The Jackson Laboratory and co-senior author of the work with Steven Reilly of Yale, and Pardis Sabeti of the Broad. In a paper published in Oct.
Now researchers at the Broad Institute of MIT and Harvard have used cutting-edge continuous laboratory evolution and engineering methods to develop improved versions of the gene-editing tool. Reverse transcriptase proteins that copy RNA templates into strands of DNA are found naturally in all plant and animal cells and in many viruses.
The automation of processes, workflows, and data enables laboratories to reduce downtime, increase scalability, and optimize efficiency. Automation provides the time and space for biotech R&D laboratories to focus on innovations and improvements, which is crucial to a laboratory’s success.
DNA topoisomerase IIβ (TOP2β/180; 180 kDa) is a nuclear enzyme that regulates DNA topology by generation of short-lived DNA double-strand breaks primarily during transcription. TOP2β/180 can be a target for DNA damage-stabilizing anticancer drugs, whose efficacy is often limited by chemoresistance.
However, with so many individual processes involved in NGS library preparation, you might think that automating this workflow requires several instruments costing large amounts of laboratory space. Enter firefly ®. What benefits can you expect to see from making the switch to automated liquid handling with firefly?
After some time in that role and launching several products, I received a call from Bill Banyai and Bill Peck, or ‘The Bills’ as we call them, who were building a company around technology that creates DNA by ‘writing’ it on a silicon chip. We’ve miniaturised the chemical process to making DNA and synthesize or ‘write’ DNA on a silicon chip.
Credit: Jane Ades, National Human Genome Research Institute, NIH Type 2 diabetes (T2D) tends to run in families, and over the last five years the application of genomic technologies has led to discovery of more than 60 specific DNA variants that contribute to risk.
Dr Chowell spent a year as a visiting graduate student at the Moe Win Laboratory for Information and Decision Systems at MIT.

For example, once considered incurable and terminal, patients with sickle cell disease may reach new summits in their lives with gene editing technologies such as CRISPR to repair affected DNA and, in some cases, functionally cure the condition. Modifying and expanding the cells in a GMP laboratory.
The Higgs boson was discovered at CERN, a sprawling particle physics laboratory that cost more than $10 billion to build. This last variable could be just about anything; there are proteins that bind to other proteins (like antibodies), cut other proteins (proteases), or bind DNA (transcription factors).
Astronauts face a myriad of ongoing and long-term risks that include reduced muscle mass and bone density loss, accelerated cancer cell metastasizing, and DNA damage. The primary hazards in space, such as microgravity and cosmic radiation, have serious implications for human health.
A research team led by Xianghong Jasmine Zhou, PhD, professor of Pathology and Laboratory Medicine at the David Geffen School of Medicine at UCLA, has made an important advancement to address one of the major challenges in cell-free DNA (cfDNA) testing, also known as liquid biopsy.
Beyond simply backing great science (separating the wheat from the chafe), setting a company up properly is critical, and early choices can get locked into the DNA of the company. Some continue to do so today, unfortunately, but there appears to be less of it happening. Second, great teams of truly experienced leaders are scarce.
The underlying assumption of most gene therapy procedures, irrespective of the disease being targeted, is that restoration of a wild-type DNA sequence will alone be sufficient to normalise the phenotype of the individual. Surely, then, a correct set of DNA plans will ensure a correctly functioning cell?
Adeno-associated virus (AAV) is a single stranded, Parvoviridae DNA virus, packaged in a non-enveloped icosahedral capsid, that can be used to express genes of interest in cell and animal models. This post was contributed by guest blogger Didem Goz Ayturk with edits and updates from Addgenies Karen Guerin and Susanna Stroik.

This last variable could be just about anything; there are proteins that bind to other proteins (like antibodies), cut other proteins (proteases), or bind DNA (transcription factors).
However, some groups will decide to complete this stage within their own laboratories. After binding, the transposase enzyme will excise the flanked section of DNA (termed the transposon) and insert it into sites in the genome at specific target sequences. We talk about personalised medicine; how about personalised host cell lines?
Gene therapy requires DNA and/or RNA delivery and analysis, and while most ongoing research involves therapies being delivered in vivo via adeno-associated viral (AAV) vectors, other in vivo delivery methods are on the rise. The process utilizes short synthetic DNA fragments called primers to choose a section of the genome to be amplified.
Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. Its presence elsewhere would indicate something is wrong. But what, exactly?”
However, with so many individual processes involved in NGS library preparation, you might think that automating this workflow requires several instruments costing large amounts of laboratory space. What benefits can you expect to see from making the switch to automated liquid handling with firefly?
The Jackson Laboratory, who has developed 3 KAND mouse models and 9 KAND cell models, is working on Prime/base gene editing, which replaces large sections of mutant KIF1A DNA with the healthy sequence. Simran Kaur’s 2023 conference talk briefly describes the KIF1A mini-gene approach.
The cell’s nucleus, containing compacted DNA, is centrally positioned within the cell. It didn’t have the tools that are important for nuclear receptors, namely the ability to interact with DNA and the ability to translocate from the cytoplasm to the nucleus,” says Cheroutre. Does it modulate the signalling strength or duration?
What is the difference between a Clinical Laboratory Improvement Amendments (CLIA)-approved laboratory vs a research laboratory? The Centers for Medicare & Medicaid Services (CMS) regulates all clinical laboratory testing performed on human samples in the US through CLIA.
Spectrum and Rutgers Clinical Genomics Laboratory (RUCDR, now IBX) first identified, then introduced the nation to the key benefits of using saliva collected exclusively with the SDNA-1000 saliva collection system as a better viral diagnostic biomaterial for COVID-19 detection. ABOUT SPECTRUM SOLUTIONS AND SPECTRUM DNA.

That was so in 1977, when “intervening DNA sequences” – aka “introns” – were discovered to interrupt protein-encoding genes. Because the edits are in RNA, and not DNA, they are fleeting. The post How (and Why) the Octopus Edits its RNA appeared first on DNA Science.
Data from standard DNA and RNA sequencing approaches were integrated with mass spectrometry-based proteomics and phosphoproteomic analyses to derive more complete molecular portraits of treatment-responsive versus treatment-resistant tumors. "The These data suggest a multi-omics predictor for chemotherapy response is within reach.
At AstraZeneca and beyond we are exploring the use of cell-free DNA (cfDNA) methods to assess minimal residual disease as a possible intermediate endpoint across several disease types. To be successful, surrogate or intermediate endpoints will need to be established to accelerate the development of the new regimens.
2 Structure and function of AAV capsids in gene therapy Wild-type AAV is composed of a protein shell (capsid) that contains a single-stranded DNA genome encoding proteins involved in viral replication, structure and assembly. Dr Chelsea B Pratt is the Biopharma Segment Marketing Manager at Bio-Rad Laboratories.
But whatever the number is, it is so much larger than the number of compounds that have ever been synthesised in a chemistry laboratory (which is over the order of 10^12) that the limitation of virtual screening instantly becomes clear: we are hardly scratching the surface of the small molecule diversity.
Illumina , the world’s leading DNA sequencing and array-based technologies company, is partnering with Sequoia Capital China, an investment firm, to launch a life sciences incubator in China. All will be in a fully operational laboratory space in Shanghai, China. The first funding cycle will start in the Fall of 2021. Here’s the link.
Prior to the new study, the laboratories of Dr Michael Levin, Vannevar Bush Professor of Biology at Tufts University School of Arts & Sciences, and Dr Josh Bongard at the University of Vermont, created multicellular biological robots from frog embryo cells, named xenobots.
Although the estate was undoubtedly pretty, the Hall had seen better days and was rather dominated by a 1950s building that provided laboratories for the light engineering company that had owned the site. Only later were the first computers established to automate intelligence gathering.
I have also learned a lot about the nuances of micropipettes that I would have never learned at school.” — Sheridan Moore , Research Associate Intern, Laboratory Sciences “My favorite part about interning at Altasciences is the potential for creating a long, meaningful career that I would be passionate about.
Impurities or degradants that exceed qualification thresholds and have not been adequately tested in Good Laboratory Practices (GLPs) toxicology studies are often encountered during development. In addition, this guidance focuses on DNA reactive substances that could potentially cause cancer. link] ICH M7 (R2)- Q&A.
The analysis of circulating tumor DNA (ctDNA) in a liquid biopsy can also permit genotyping and help monitor the effectiveness of chemotherapy. In hematological cancers, a liquid biopsy can help identify mutations otherwise absent in a tissue biopsy.
The new cells are then grown in high numbers in a laboratory and then are re-administered to the patient, where the genetically modified cells will attack more specific cancer cells. This technology extensively utilizes immunofluorescence and flow cytometry technology, which is a platform offered in our laboratories.
