Cytoskeleton, Inc. Tubulin protein (biotin): porcine brain, 5x20 µg
Supplier: Cytoskeleton, Inc. T333PA
Porcine brain tubulin (>99% pure) has been modified so that random surface lysines contain a covalently linked, long-chain biotin derivative. A long-chain biotin derivative was selected for this procedure because it allows the biotin molecules to be spaced far enough away from the tubulin protein so as not to interfere with its activity, e.g., ligand binding to SPA beads or other streptavidin based reagents. Biotin labeled tubulin is supplied as a lyophilized powder.
