This assay has high sensitivity and excellent specificity for detecting Human/Mouse/Rat ACTB (Beta Actin). The assay range is from 1.56 to 100 ng/ml (Sandwich kit) with a sensitivity of 0.55 ng/ml. There is no detectable cross to reactivity with other relevant proteins. Activity loss rate and accelerated stability test ect have been conducted to guarantee the best performance of the products after long storage and delivery.

• High sensitivity and specificity
• Perfect reproducibility and consistency across batches
• Quality control with three-level inspections
• Wide range of targets/species available
• Intra-Assay: CV <10%, Inter-Assay: CV <12%

Beta-actin (gene name ACTB) is one of the two nonmuscle cytoskeletal actins. Actins are highly conserved proteins that are involved in cell motility, structure and integrity. Alpha actins are a major constituent of the contractile apparatus. In a neoplastic cell line resulting from treatment of cultured human diploid fibroblasts with a chemical mutagen, Leavitt et al. (1982) observed a mutant form of beta actin. Toyama and Toyama (1984) isolated and characterized lines of KB cells resistant to cytochalasin B. They found that one resistant line had an alteration in beta-actin. Such cells bound less cytochalasin B than did parental KB cells. The authors suggested that the primary site of action of cytochalasin B on cell motility processes is beta-actin.
