Applications

Fluorimetrical Analysis of actin dynamics (e.g. kinetics of polymerization, nucleation, depolymerization)

 

Description

   

Protein

Pyrene Actin

Origin

Skeletal muscle alpha actin, rabbit

Molecular mass

42kDa

Protein description

G-actin from rabbit skeletal muscle is a single chain polypeptide with a molecular weight of 42kD consisting of 375 amino acids. Pyrene-Actin is chemically modified G-actin, carrying a pyrenyl group covalently bound to Cys374 at the C-term of the molecule.

The actin polymerization can be induced simply by mono- or divalent cations (in-vitro conditions) and the actin kinetic can then be measured fluorometrically. Fluorometry with Pyrenyl-Actin is standard  method  to study the effect of ligands on actin kinetics.

Conjugation ratio

Pyrene Actin (100%)  is 100% labelled and thus has a dye/protein molar ratio of 1.
