Western blot shows lysates of COLO 205 human colorectal adenocarcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human A33 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3080) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). A specific band was detected for A33 at approximately 45 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background

Human A33, also known as GPA33, is a 43 kDa type I transmembrane glycoprotein that belongs to the CTX (cortical thymocyte marker in Xenopus) family of cell adhesion molecules within the immunoglobulin superfamily. Other family members include CXADR, ESAM, BT-IgSF, CD2, and JAM-A, -B, and -C. The extracellular domain (ECD) of human A33 is 214 amino acids (aa) in length and contains one V-type and one C2-type Ig-like domain. This ECD shares 80%, 74%, and 71% aa sequence identity with canine, bovine, and mouse A33 ECD, respectively. A33 is likely to be involved in cell-cell adhesion between epithelial cells.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
