Product Overview
Clone 30C81 is a rabbit monoclonal antibody that recognizes cellular retinoic acid-binding protein 2 (gene CRABP2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 15.7 kDa, and the supplier reports an observed band at about 14 kDa.
Cellular retinoic acid-binding protein 2 (CRABP2) binds all-trans retinoic acid in the cytoplasm and carries it into the nucleus. There it delivers the ligand to retinoic acid receptors, enhancing their transcriptional activity, so CRABP2 is studied in retinoid signaling, skin biology and cancer.

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).
