Merck, A5316-.5ML, Monoclonal Anti-β-Actin antibody produced in mouse

Actin is a highly conserved protein that is a major component of both the cytoskeletal and contractile structures in all cell types. It varies in amount, being related to the type of differentiation and to the functional state of cells and tissues. Actin can be found in two different forms of aggregation, the globular or the fibrillar state, and at least six distinct isoforms occur in vertebrates. The actins exhibit over 90% sequence homology, but each isoform has a unique NH2-terminal sequence. The isoforms are comprised of three α actins (skeletal, cardiac, smooth), one β actin (β-non-muscle) and two γ actins (γ smooth muscle and γ non-muscle). ACTB (actin β) gene codes for β-actin. It is a cytoskeletal housekeeping protein. It is present in the cytoplasm. The ACTB gene is located on human chromosome 7p22.1. Monoclonal Anti-β-Actin (mouse IgG2a isotype) is derived from the AC-74 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.
