Deciding between mRNA vs DNA transient transfection influences your experiment’s success. mRNA delivers rapid, promoter-independent expression without the risk of genomic integration, making it ideal for non-dividing or hard-to-transfect cells. With optimized reagents and careful handling, mRNA transfection offers unmatched speed, safety, and precise control.

So, you have successfully cloned your gene of interest and are eager to purify buckets of protein. No matter your eventual application—kinetic experiments using a SPR instrument, structural analysis using X-ray crystallography, or any other experiment—you’ll need to express your protein first. Now, it’s time to put your expression plasmid into E. coli and get…
Dear Aunt Yersinia, A very annoying postdoc in our group keeps telling me off for spinning E.coli at 13K in a tabletop centrifuge. The postdoc claims that high speed damages cytoskeleton and this will reduce my transformation frequency. But I don’t believe her as the cells are cushioned by water during centrifugation. Can you tell…
Dear Aunt Yersinia, I work with a yeast vector where my gene is under a Gal promoter. My boss told me to grow yeast in medium with sucrose, and then add galactose to induce the promoter. I did it, but my protein is not induced; the Western blot is empty. I sequenced a part of…
