As biochemists, we routinely run SDS-PAGE to analyze our proteins. Imagine the time and effort you are going to save when you can run every gel to perfection.
Two years ago, all I knew was third BASE in my baseball field and the cutter ball from the pitcher. Now, I know a lot more about lab-based BASES and cutters: REBASE and NEBcutter. While they sound like baseball terms, REBASE and NEBcutter are tools for working with restriction enzymes. Read on to find out…
Bubbles isn’t just the name of my favorite cartoon character from Power Puff girls, or just the best activity for a kid to play with, in general. In my adult world, they stand for a whole lot more, but can still cause extreme emotions. At the lab bench, seeing bubbles brings happiness or sadness depending…
Recently BsB author Yevgeniy Grigoryev shared a total RNA isolation protocol. The one I use is even simpler—no expensive Trizol, which is a mix of phenol and some salts, all that is required is some Tris, SDS and phenol/chloroform mix. I have never used this protocol on non-yeast cells but I am almost sure that…
All over the world, molecular biologists are tragically wasting hours of their life running DNA gels using tris-based conduction buffers like TBE or TAE. These buffers are known to overheat at high voltages, causing problems with gel integrity, sample denaturation and more. Because of this, molecular biologists are forced to keep the voltage of their…
Ever wonder what those small colonies, like satellites, surrounding a larger E. coli colony on your LB with ampicillin plates were? Or why, when you picked that colony, it never had the plasmid you just transformed? Well, it’s because those satellite colonies are “protected” from the ampicillin by the big colony. Read on for more… Ampicillin…
