Actin Monoclonal Antibody (ACTN05 (C4)), Invitrogen™

Descripción

MA5-11869 reacts with all six known vertebrate isoforms of actin (MW ∽42kDa), and with two cytoplasmic actins (beta and gamma), which are highly homologous to each other but differ from the muscle actins by ∽25 amino acid residues. This product is highly recommended for monitoring total protein load on Western blots. Staining of formalin-fixed, paraffin-embedded tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0 for 10-20 minutes, followed by cooling at room temperature for 20 minutes. Suggested positive controls are HeLa cells and skeletal muscle. MA5-11869 is a suggested replacement to Product # 82353, clone # C4.

Actin exists as a ubiquitous protein involved with filament formation that make up large portions of the cytoskeleton. Actin filaments interact with myosin to assist in muscle contraction as well as aiding in cell motility and cytokinesis. In vertebrates there are three groups of actin isoforms: alpha, beta and gamma. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exists in most cell types as components of the cytoskeleton and as mediators of internal cell motility.
