What is protein crystallography? Whether you are about to enter the world of protein crystallography or work with a protein crystallographer on your grant, this article will be useful.
There is something about kinases that resemble ghosts. Their effects reveal their presence, but they can be difficult to catch. With a low abundance of hundreds or even tens of molecules per cell, they are difficult to detect using conventional methods such as Western blotting or mass spectrometry (MS). However, you will need to detect…
Does the term “ultracentrifuge” make your heart begin to race? Fear not! This article will provide you with tried and true tips on how to handle this piece of machinery like a boss.
As a biologist you will no doubt have seen Enzyme Commission (EC) numbers. An EC number is group of four numbers separated by periods in papers discussing enzymes…something like this: EC 1.1.2.1. But do you know what these numbers mean? Or where they came from? Or why we use them? If not, I will aim…
Studying nucleic acid interactions with proteins can be accomplished using a rapid and efficient electrophoretic mobility shift assay (EMSA). This method is essentially an agarose gel electrophoresis technique that detects protein:nucleic acid interactions, as the mobility of the labeled nucleic acid will be retarded if bound to a protein (compared to unbound DNA). A lesser-known…
Blocking is the essential third wheel in any antibody/antigen relationship. Correct blocking buffer can perfect your antibody’s ability to bind its antigen, while bad blocking can make specific antibody binding near impossible. Don’t let bad blocking be a stumbling block in your Western blot experiments – read on to find out what blocking achieves and…
