Please Note: Optimal dilutions should be determined by each laboratory for each application.

Scientific Data Examples for Human HSPA8/HSC71 Antibody

	Western Blot Detection of Human HSPA8/HSC71 by Western Blot. Western Blot shows lysates of A431 human epithelial carcinoma cell line, K562 human chronic myelogenous leukemia cell line and Jurkat human acute T cell leukemia cell line. PVDF membrane was probed with 0.01 µg/ml of Rabbit Anti-Human HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB11819) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for HSPA8/HSC71 at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.
	Simple Western Detection of Human HSPA8/HSC71 by Simple Western^TM. Left: Simple Western lane view shows lysates of K562 human chronic myelogenous leukemia cell line, loaded at 0.1 mg/ml. A specific band was detected for HSPA8/HSC71 at approximately 70 kDa (as indicated) using both 1 µg/ml and 5 µg/ml of Rabbit Anti-Human HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB11819) followed by HRP-conjugated Goat Anti-Rabbit Secondary Antibody (042-206). This experiment was conducted under reducing conditions and using the 12-230kDa separation system. Right: Simple Western electropherogram showing the same Rabbit Anti-Human HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB11819) tested at 1 µg/ml (blue line) and 5 µg/ml (green line) in the K562 human chronic myelogenous leukemia cell line.
	Immunohistochemistry Immersion fixed paraffin-embedded sections of human lung HSPA8/HSC71 was detected in immersion fixed paraffin-embedded sections of human lung using Rabbit Anti-Human HSPA8/HSC71 Monoclonal Antibody (Catalog # MAB11819) at 1 µg/ml overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (VCTS021). Tissue was stained using the HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008) and counterstained with hematoxylin (blue). Specific staining was localized to the cytoplasm and nucleus.

Background: HSPA8/HSC71

Heat shock cognate 71-kDa protein (HSPA8), also referred to as HSC70, is a member of the heat shock protein 70 (HSP70) family, with a molecular weight of approximately 71 kDa. HSPA8 is an ATP-dependent molecular chaperone ubiquitously expressed in eukaryotic cells and plays a critical role in protein homeostasis. It facilitates the folding of nascent polypeptides, the assembly and disassembly of protein complexes, and the translocation of proteins across membranes. Additionally, HSPA8 is involved in the targeting and degradation of misfolded or damaged proteins via the ubiquitin-proteasome pathway and lysosomal-associated degradation. Beyond its canonical chaperone functions, HSPA8 participates in cellular processes such as autophagy, stress response, and clathrin-mediated endocytosis. Dysregulation of HSPA8 expression or activity has been implicated in various pathological conditions, including neurodegenerative disorders such as Alzheimer's and Parkinson's diseases, where aberrant protein aggregation is a hallmark feature. The multifunctionality and essential cellular roles of HSPA8 underscore its utility as both a biomarker and a potential therapeutic target in a range of diseases.
