Protein

Atto550-Actin

Origin

Skeletal muscle alpha actin, rabbit

Molecular mass

42kDa

Protein description

Actin from rabbit skeletal muscle is a single chain polypeptide with a molecular weight of 42kD consisting of 375 amino acids. ATTO550-Actin is chemically modified G-actin with an ATTO550 fluorescent group covalently bound to lysine residues. 
ATTO550-Actin (λex 550nm, λem 576nm) possesses the polymerization properties of native G-actin. 

Conjugation ratio

This product is supplied with a degree of labelling (DOL) of ~0.3 and is thus ready for TIRF microscopy. 

Form

Lyophilized, ready-to-use.
