Scientific Data Images for Human HAX-1 Antibody

Detection of Human HAX-1 antibody by Western Blot.

Detection of Human HAX-1 by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line and HepG2 human hepatocellular carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human HAX-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5458) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for HAX-1 at approximately 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
HAX-1 antibody in HepG2 Human Cell Line by Immunocytochemistry (ICC).

HAX‑1 in HepG2 Human Cell Line.

HAX-1 was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line using Goat Anti-Human HAX-1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5458) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

Background: HAX-1

HAX-1 (HCLS1-associated protein X-1; also HS1-binding protein1) is a 34‑35 kDa intracellular protein with structural similarity to Bcl-2 family proteins. It is ubiquitously expressed, and participates in a variety of cell-specific functions. HAX‑1 blocks cardiomyocyte apoptosis via caspase‑9 inhibition, downregulates conjugated bile acid secretion via BSEP binding, and via PKD2, transmitts integrin signals to the ER. Human HAX-1 is 279 amino acids (aa) in length and contains two Bcl-2 homology regions (aa 37‑56 and 74‑89), a PEST domain (aa 104‑117) and a potential transmembrane segment (aa 261‑279). HS-1 is found mostly in the mitochondria. HAX-1 is also cleaved by caspase-3 at Asp127. Over aa 2‑261, human HAX-1 shares 81% aa identity with mouse HAX-1.
