Beta-actin (ACTB) is a constitutively expressed cytoskeletal housekeeping protein widely adopted as a standard endogenous loading control for normalizing protein expression data in biochemical research. CSB-MA000091M2m is a mouse monoclonal IgG1 antibody generated against a synthetic peptide from human ACTB (residues 1–50), purified via Protein G affinity chromatography with purity above 95% to guarantee consistent batch-to-batch performance and low non-specific background. Designed as a reliable loading control antibody, it demonstrates broad cross-species reactivity covering human, mouse, rat, and rabbit samples. Western blot detects a distinct 42 kDa target band across diverse cell lysates and multiple organ tissues, delivering clear signals at an ultra-high dilution up to 1:1280000 and reliably detecting lysate loads as low as 0.3125 μg. Validated for ELISA and Western blot applications, this antibody provides flexible working dilution ranges and delivers stable, reproducible results, serving as a dependable reference standard for quantitative proteomics and cell biology research.
