Product Overview
Clone 23C19 is a rabbit monoclonal antibody that recognizes alpha-crystallin A chain (gene CRYAA) in human, mouse and rat samples and is validated for Western blot and ICC/IF. The predicted molecular weight is 19.9 kDa, and the supplier reports an observed band at about 17 kDa.
αA-crystallin (CRYAA) is a small heat shock protein and a major structural protein of the eye lens, where it helps maintain transparency and refractive index. It also acts as a chaperone that prevents protein aggregation under stress, and CRYAA mutations cause congenital cataract.

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).
