Scientific Data Images for Human S100A1 Antibody
Detection of Human S100A1 by Western Blot.
Western blot shows lysates of human heart and brain tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human S100A1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4476) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for S100A1 at approximately 10 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.Applications for Human S100A1 Antibody

Background: S100A1
S100A1 (also S100 alpha) is a 10 kDa member of the S100 family, EF-hand superfamily of Ca-binding proteins. It is expressed by striated muscle, endothelium and chondrocytes. Intracellularly, S100A1 regulates cytosolic Ca levels, and is part of the Hsp70/Hsp90 mutlichaperone complex that protects against protein denaturation. Extracellularly, it exists as both a homodimer and heterodimer with S100B, S100A4 and S100P, may bind to RAGE, and blocks apoptosis. Human S100A1 is 94 amino acids (aa) in length. It contains two EF-hand motifs (aa 13‑48 and 50‑85) and a Ca-dependent protein interaction site (aa 89‑91). There may be one alternate start site 53 aa upstream of the standard start site. Full-length human S100A1 shares 93% and 98% aa identity with mouse and canine S100A1, respectively.
