Western blotting uses electrophoresis and antibody-epitope affinity to give a semi-quantitative and (theoretically) clear measure of protein abundance. It’s a long procedure, filled with many steps—and even more room for error. Learning to troubleshoot certain problems is incredibly important for continued success with this technique. So what do you do when your final imaged product…
While many scientists are methodical and precise, some of us like to live on the edge. Read a protocol all the way through? No thanks, I’ll take my chances and guess what concentration of HCl I should use. Label my tubes with the correct content? Puh-lease – it’s much more exciting deducing which is which…
The importance of epigenetics in biology is increasingly acknowledged (if you’re not convinced yet, read my crash course). One commonly studied epigenetic mark is CpG methylation: cytosines that are directly followed by a guanine nucleotide (indicated by CpG), can be methylated, unlike non-CpG Cs. Since attachment of a methyl group to a cytosine can affect…
You may have heard about a breakthrough cancer therapy that engineers patient’s immune cells to fight their cancer using chimeric antigen receptor (CAR)-T cells. If you don’t live in the world of immunology, you may not know what a CAR is, or what it is used for. Here you’ll find a brief guide to CARs,…
If you were to peek into a protein biochemist’s bag of tricks, what would you find? A mortar and pestle for collecting samples, some columns for isolating proteins and a mass spec instrument? Perhaps. But what about those little eppendorf tubes full of enzymes and helpful molecules? Certainly, each scientist has his/her own favorite. Here…
Figuring out what’s what When studying cells and cell subsets (and cell sub-subsets, and so on!!) we need ways to identify and classify every single cell. This will allow us to individually analyse each population and, for example, help to discover their role in health and disease. A principal way we do this is by looking…
