Product Overview
Clone ABDI-19 is a rabbit monoclonal antibody that recognizes serpin A9 (gene SERPINA9) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 46.6 kDa, and the supplier reports an observed band at about 47 kDa.
Serpin A9 (SERPINA9, also called centerin or GCET1) is a serpin expressed in germinal center B cells. In vitro it inhibits trypsin and trypsin-like serine proteases and, less efficiently, plasmin and thrombin; it is studied in B-cell and lymphoma biology.

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).
