Product Overview
Clone 25P61 is a rabbit monoclonal antibody that recognizes protein disulfide-isomerase (gene P4HB) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 57.1 kDa, and the supplier reports an observed band at about 57 kDa.
Protein disulfide isomerase (PDI, P4HB) is an abundant endoplasmic reticulum enzyme that forms, breaks and reshuffles disulfide bonds in newly made proteins and can also act as a chaperone. It is the β subunit of collagen prolyl 4-hydroxylase and of the microsomal triglyceride transfer protein, and is studied in protein folding and ER stress.

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).
