Detection of Human/Mouse/Rat HSPA8/HSC71 antibody by Western Blot.

Detection of Human/Mouse/Rat HSPA8/HSC71 by Western Blot.

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, NIH-3T3 mouse embryonic fibroblast cell line, and NRK rat normal kidney cell line. PVDF membrane was probed with 0.1 µg/mL of Mouse Anti-Human/Mouse/Rat HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB4148) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for HSPA8/HSC71 at approximately 75 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
HSPA8/HSC71 antibody in HeLa Human Cell Line by Immunocytochemistry (ICC).

HSPA8/HSC71 in HeLa Human Cell Line.

HSPA8/HSC71 was detected in immersion fixed HeLa human cervical epithelial carcinoma cell line using Mouse Anti-Human/Mouse/Rat HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB4148) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei, especially nucleoli. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
HSPA8/HSC71 antibody in Human Kidney by Immunohistochemistry (IHC-P).

HSPA8/HSC71 in Human Kidney.

HSPA8/HSC71 was detected in immersion fixed paraffin-embedded sections of human kidney using Mouse Anti-Human/Mouse/Rat HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB4148) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to epithelial cells in convoluted tubules.

Detection of Mouse HSPA8/HSC71 antibody by Simple WesternTM.

Detection of Mouse HSPA8/HSC71 by Simple WesternTM.

Simple Western lane view shows lysates of NIH‑3T3 mouse embryonic fibroblast cell line, loaded at 0.2 mg/mL. A specific band was detected for HSPA8/HSC71 at approximately 72 kDa (as indicated) using 1 µg/mL of Mouse Anti-Human/Mouse/Rat HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB4148). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: HSPA8/HSC71

The 70 kDa heat shock proteins (HSP70s) are a highly conserved family of stress response proteins. The HSP70 family of proteins contains both heat/stress inducible and constitutively expressed members known as heat shock cognate proteins. Heat Shock 70 kDa Protein 8 (HSPA8), also known as Heat Shock Cognate Protein 71 (HSC71), HSC70, HSP73, HSPA10 and LPS-associated protein 1 (LAP1), is a 646 amino acid (aa) heat shock cognate protein. Many HSPs function as molecular chaperones, facilitating the folding of other cellular proteins. HSPA8 plays an important role in cells by transiently associating with nascent polypeptides to facilitate correct folding. HSPA8 is a ubiquitously expressed protein and rapidly translocates from the cytoplasm to the nucleus in response to heat shock. Two alternatively spliced variants have been identified. This antibody detects isoform 1 but not isoform 2 (HSC54). Human HSPA8 shares greater than 99% identity with mouse and rat HSPA8.

    Simple Western run of MAB4148 on rat B103 cells (~250, 750, and 1500 cell equivalents per lane [left to right]) using 5 µg/mL of antibody final. Overall, the signal is clean, although the band at 56 kDa was not expected and some cross-reactivity is seen with the 230-kDa fluorescent migration control.
