A T4 phage can hold 171,000 bases of DNA or other molecules, including proteins and RNA. For context, the AAV9 that is often used in gene therapies has a packaging limit of 4,700 DNA bases.) It uses single-molecule RNA fluorescence to measure mRNAs and fluorescent reporters to measure the proteins. Paper by Sha G. in Nature.

Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. ” Quanta Magazine.

In the case of semaglutide, those cells are Saccharomyces cerevisiae— also known as Baker’s yeast — engineered to secrete a peptide precursor that is later purified, chemically modified, packaged into an injectable or tablet form, and then shipped around the world. Continuing this method may not scale.

The researchers first compared the editing efficiency of different versions of IscB when coupled with 'ωRNA,' which guides the enzyme to the right spot on the DNA. A particular variant, named IscB*-ωRNA*, had the highest editing efficiency across multiple different sites in the genome. Read more in Nature Methods.
