Anti-γ-Actin (ACTG1) Antibody

42-43kDa

Actin is a 43kDa highly conserved structural protein. There are three main actin isotypes (alpha,beta and gamma) which show >90% amino-acid (aa) homology between isotypes and >98% homology within members of a particular isotypic group. The majority of the isotype heterogeneity is located in the amino-terminal 30 aa. The different actin isotypes have been shown to behave very differently in vitro and in vivo. Recent studies describe differential subcellular localization of gamma-actin and isotype specific binding of actin associated proteins. {Pardo et al, 1983, Cell 32:1093-1103 & Otey, CA et al 1986 J Cell Biol 102:1726-1737, Bassell et al, 1998, J Neurosci 18:251-265 {available online}. Furthermore, there are at least six actin isoforms in vertebrates: cardiac alpha-actin and skeletal-alpha actin (expressed in striated muscle), vascular alpha-actin and enteric gamma-actin (expressed in smooth muscle), and cytoplasmic beta- and gamma-actins.{http://www.cbil.upenn.edu/MTIR/gammaActin_E-toc.html}

Western Blot: 1:500-1:2,000 or greater; non-specific bands can occur when primary antibody is overloaded. Blocking with purified milk proteins preferred over commerical concentrated milk solutions. Detects a 42-43kDa band. Specificity for gamma actin determined by 2D gel electrophoresis.

Immunocytochemistry: 1:500-1:2,000. Cultured cells fixed with PFA, then permeabilized with methanol.

Immunohistochemistry: 1:500-1:2,000. Tissues frozen and then fixed with PFA followed by Triton permeabilisation. 10% buffered formalin fixed tissues have also been used.

Optimal working dilutions must be determined by the end user.

Recognizes actin, gamma. Specificity for gamma actin determined by 2D gel electrophoresis.

Serum. Liquid, containing no preservatives.

Unpurified
