Description
Bacteriorhodopsin (BR) is a 7-transmembrane protein that acts as a light-driven proton pump in archaebacteria. Due to its covalently bound colored ligand, BR is widely used as a control membrane protein, for example for crystallization assays and biochemical/biophysical experiments. We provide BR of high purity, prepared as purple membrane patches from Halobacterium salinarum.
