Protein Isolation How to Choose Membrane Protein Isolation Kits
Plasma membrane (PM) proteins play a critical role in a variety of physiological and pathological processes. Signal transduction, molecular transport and cell-cell interactions are all mediated by PM proteins. PM proteins include a variety of important proteins such as neurotransmitter receptors, G-proteins, carriers, voltage-gated ion channels, CD antigens and many drug targ...
Artifacts in IHC The usual suspects - part I
After a few intense days of meticulous tissue washes and antibody incubations my staining is finally ready. I am staring at it down the microscope. I enjoy what I see: a dark brown color exactly where I expect to see it! Am I good or what? I give myself a figurative pat on the back and an imaginary high five. Excited and proud, I call my supervisor who glares intently at it and...
