Scientific Data Images for Human A33 Antibody

Detection of Human A33 by Western Blot.

Western blot shows lysates of HT-29 human colon adenocarcinoma cell line and COLO 205 human colorectal adenocarcinoma cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human A33 Monoclonal Antibody (Catalog # MAB30802) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for A33 at approximately 37 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of Human A33 by Simple WesternTM.

Simple Western lane view shows lysates of HT-29 human colon adenocarcinoma cell line, COLO 205 human colorectal adenocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for A33 at approximately 40 kDa (as indicated) using 50 µg/mL of Mouse Anti-Human A33 Monoclonal Antibody (Catalog # MAB30802) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

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.
