Product Overview
Clone ABHC-3 is a rabbit monoclonal antibody that recognizes alpha-crystallin B chain (gene CRYAB) in human and rat samples and is validated for Western blot, IHC, ICC/IF and immunoprecipitation. The predicted molecular weight is 20.2 kDa, and the supplier reports an observed band at about 22 kDa.
αB-crystallin (CRYAB) is a small heat shock protein found in the lens and in muscle, heart and brain. As a chaperone it binds partially unfolded proteins to prevent aggregation, and it is studied in cataract, myopathies and neurodegeneration, where it often accumulates in protein inclusions.

Samples with a confirmed band (WB): rat eye tissue, rat heart tissue, mouse eye tissue, mouse heart tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 12% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human kidney tissue, human renal cancer tissue, rat heart tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Synthetic peptide based on the sequence of human CRYAB.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt describes alpha-crystallin B chain as secreted and also located in the cytoplasm, nucleus and lysosome. Tissue expression noted by UniProt (human): Lens as well as other tissues. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
