Description

   

Protein

NBD-Actin

Origin

Skeletal muscle alpha actin, rabbit

Molecular mass

43kDa

Protein description

G-actin from rabbit skeletal muscle is a single chain polypeptide with a molecular weight of 42kD consisting of 375 amino acids. NBD-Actin is chemically modified G-actin.

The first modification step results in NEM-actin (N-ethylmaleimide actin). Subsequent covalent conjugation of 4-Chloro-7-Nitrobenz-2-Oxa-1,3-Diazole (NBD) to Lys372 yields green fluorescent NBD-Actin.

Optical properties: Abs. max. 337nm; Em. max. 512nm

Conjugation ratio

DOL=0.8.
