Protein description
|
Biotin-Actin from rabbit skeletal muscle is chemically modified α-actin by esterification of lysine residues with biotin. The advantage of Biotin-Actin from Hypermol is, that it is equipped with a ~20 Å spacer, which renders the Biotin group to be readily available for antibody detection in all suitable techniques (ELISA, Western Blotting etc.).
|
Conjugation ratio
|
The degree of labelling (DOL) of Biotin-Actin is approx. 1 .
