Product Overview
Clone 19B58 is a rabbit monoclonal antibody that recognizes B-cell receptor-associated protein 31 (gene BCAP31) in human and mouse samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 28.0 kDa, and the supplier reports an observed band at about 25 kDa.
BCAP31 (BAP31) is an abundant multi-pass membrane protein of the endoplasmic reticulum that acts as a chaperone and sorting factor. It controls ER export or retention of membrane proteins, helps route misfolded proteins to ER-associated degradation, and when cleaved by caspase-8 it can relay apoptotic signals between the ER and mitochondria.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
