often used reference proteins for cytosolic proteins are b-actin or a-tubulin; however, which reference protein to use for membrane fraction? receptor proteins are not suitable as they normally have a vivid turnover. what about membrane skeleton proteins (ankyrin, spectrin, ezrin protein family, other actin-binding proteins etc)? Or is also b-actin to use as it is linked to the plasma membrane?
