synthetic actin C-terminal peptide Ser-Gly-Pro-Ser-Ile-Val-His-Arg-Lys-Cys-Phe, attached to a Multiple Antigen Peptide (MAP) backbone.

General description

The antibody recognizes an epitope located on the C-terminal end of actin conserved in all actin isoforms. It specifically labels actin in a wide variety of tissues and species. The epitope recognized by the antibody is resistant to formalin-fixation and paraffin-embedding. Zinc-formalin, B5, ethanol, methacarn, Brunnel′s or Bouin′s solutions may also be used as fixatives.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.


Monoclonal anti-actin antibody was used for western blot analysis of Cos-7 cell lysates to ensure equal protein loading.

Western blot analysis of MDCK cell lysates were performed using monoclonal anti-actin antibody as a primary antibody.
