Description

Description: The DATK32 monoclonal antibody binds to a combinatorial epitope of mouse LPAM-1 (alpha4beta7), which is a heterodimer of the the 154 kDa alpha4 subunit and the 130 kDa beta7 subunit. In mouse, the beta7 subunit is found on the majority of mature lymphocytes and a small population of thymocytes and bone marrow cells. LPAM-1 is an integrin involved in the transendothelial migration of lymphocytes across high endothelial venules (HEV), and is know to bind several ligands including MAdCAM-1, VCAM-1 and fibronectin. Binding of the DATK32 monoclonal antibody has been shown to induce aggregation of the CD8+ T cell lymphoma TK1, and block LPAM-1-mediated cell adhesion. Applications Reported: This DATK32 (DATK-32) antibody has been reported for use in flow cytometric analysis. (Please use Functional Grade purified DATK32 (DATK-32), cat. 16-5887, in functional assays.). Applications Tested: This DATK32 (DATK-32) antibody has been tested tested by flow cytometric analysis of mouse splenocytes. This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE.

Integrin beta 7 associates with integrin alpha 4 (CD49d) to form the alpha 4 beta 7 integrin LPAM-1, expressed on intraepithelial lymphocytes. It also associates with alpha E (CD103) to form the alpha E beta 7 integrin HML-1, expressed on T cells adjacent to mucosal epithelium and intraepithelial lymphocytes. Ligands for LPAM-1 include VCAM-1 (CD106), MAdCAM-1 and fibronectin, while the ligand of HML-1 is E-cadherin (CD324). Integrin beta 7 plays an important role in the adhesion of leukocytes to endothelial cells promoting the transmigration of leukocytes to extravascular spaces during the inflammatory response.
