Product Overview
This rabbit polyclonal antibody targets mucosal addressin cell adhesion molecule 1 (gene MADCAM1) in human samples and is validated for Western blot. The predicted molecular weight is 40.2 kDa, and the supplier reports an observed band at about 43 kDa.
Mucosal addressin cell adhesion molecule 1 (MADCAM1) is an immunoglobulin-superfamily adhesion molecule expressed on high endothelial venules of gut-associated lymphoid tissue and intestinal venules. By binding integrin α4β7 and L-selectin it guides lymphocytes into Peyer's patches and the intestinal lamina propria, so it is central to studies of gut immune homing and inflammatory bowel disease.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|
Samples with a confirmed band (WB): human 293T cells, human A375 cells, human K562 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Immunogen
Synthetic peptide from the middle region of human MAdCAM1. Sequence identity with the mouse and rat orthologs: 61.1% and 52.8%, respectively.
Reactivity Notes
The supplier lists reactivity with human. UniProt places mucosal addressin cell adhesion molecule 1 in the membrane. Tissue expression noted by UniProt (human): Highly expressed on high endothelial venules (HEV) and lamina propia venules found in the small intestine, and to a lesser extent in the colon and spleen. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
