SEE ALSO...

BAP1 Antibody (C-4) is a mouse monoclonal IgG1 kappa light chain antibody that detects BAP1 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). BAP1 Antibody (C-4) is available in non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. BAP1, also known as BRCA1-associated protein 1, functions as a ubiquitin hydrolase essential for regulating protein degradation and maintaining cellular homeostasis. Anti-BAP1 antibody (C-4) enhances BRCA1-mediated cell growth suppression, contributing to cancer prevention. Mutations in BRCA1 gene, located on chromosome 17q, are implicated in approximately 45% of families with higher incidence of early-onset breast and ovarian cancers. BAP1 consists of 729 amino acids and interacts with other proteins, such as BARD1, which also plays a role in tumor suppression. BAP1 (C-4) antibody binding to BRCA1 and involvement in critical cellular pathways makes this product valuable for cancer research and therapeutic development.

Do you know if this antibody will work for zebrafish?

Asked by: abc123
Thank you for your question. This antibody has not yet been tested in zebrafish and so that is not a recommended species at this time. We are still gathering data to show on our website. Check back for updates!

What is a good control tissue to use for BAP1  immunohistochemistry optimisation?

Asked by: GWAT1
Thank you for your question. Any tissue that expressed BAP1 would be a good control. We suggest duodenum or testis tissue as suitable controls.

Rated 2 out of 5 by from Inconsistent staining results of BAP1 AntibodyThis antibody produces high background signal on immunostaining. Although I tried to optimize the conditions, the background was still high. Although the efficiency of antibody varies among different batches. I tried 3 different batches; only one worked but produced high background, while the other two batches did not work at all in if, despite using the same conditions.

Rated 1 out of 5 by from Inconstant staining resultsWith one batch (test sample), we obtained plausible staining results (Ventana; CC1/32min, 8' amplification, dilution 1:75/32min; nuclear loss in the tumor cells with mutation; nuclear expression in vascular endothelia and leukocytes as well as in tumors without mutation). With another batch (regularly ordered) identical staining procedures revealed strong background staining, which remained even at much higher dilutions of the antibody even in a mutated case.
