Product Overview
Clone ICG-3 is a rabbit monoclonal antibody that recognizes catenin beta-1 (gene CTNNB1) phosphorylated at Ser33/Ser37 in human and rat samples and is validated for Western blot. The predicted molecular weight is 85.5 kDa, and the supplier reports an observed band at about 92 kDa.
β-Catenin (CTNNB1) has two roles: it is a structural part of cadherin-based adherens junctions and the central effector of canonical Wnt signaling. Without Wnt, a destruction complex of APC, AXIN, CK1α and GSK3B targets it for proteasomal degradation; with Wnt, it builds up in the nucleus and activates TCF/LEF target genes. It is studied in development, stem cells and cancer.

Immunogen
Synthetic phosphopeptide around Ser33 of human beta-catenin.
Reactivity Notes
The supplier lists reactivity with human and rat. UniProt places catenin beta-1 in the cytoplasm, nucleus, cell junction and cell membrane. Tissue expression noted by UniProt (human): Expressed in several hair follicle cell types: basal and peripheral matrix cells, and cells of the outer and inner root sheaths. The samples tested by the supplier (listed above) are a practical starting point for positive controls. Because the antibody is phospho-specific, signal depends on the phosphorylation state of the sample; a phosphatase-treated lysate is a useful negative control.

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).
