Scientific Data Images for Human A33 Antibody
Detection of A33 in HT‑29 Human Cell Line by Flow Cytometry.
HT-29 human colon carcinoma cell line was stained with Mouse Anti-Human A33 Monoclonal Antibody (Catalog # MAB30801, filled histogram) or Mouse IgG2B isotype control antibody (MAB0041, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (F0102B). Staining was performed using our Staining Membrane-Associated Proteins protocol.Applications for Human A33 Antibody

Background: A33
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-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 is 80%, 74% and 71% aa identical to canine, bovine and mouse A33 ECD, respectively. A33 is likely to be involved in cell-cell adhesion between epithelial cells.
