ATTO514-Actin for TIRFM (non-muscle) - 2x50µg

Protein

ATTO514-Actin

Origin

Non-muscle  β/γ from brain, porcine

Molecular mass

42kDa

Protein description

Actin from rnon-miscle sources are a mixture of β/γ non-muscle actins. These isoforms are  single chain polypeptides with a molecular weight of 42kD consisting of 375 amino acids. ATTO514-Actin is chemically modified G-actin with an ATTO514 fluorescent group covalently bound to lysine residues. ATTO514-Actin (λex 511nm, λem 533nm) 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-to-use for TIRFM and other high-or super-resolution imaging techniques..
