FC - Quality tested
IHC, IP - Reported in the literature

Application Notes:

Additional reported applications (for the relevant formats) include: in vitro and in vivo blocking of cell adhesion1-4, in vitro induction of TK1 cell aggregation1, immunoprecipitation4, and immunohistochemical staining of frozen sections5. It has been reported that the DATK32 mAb is able to block α4β7 mediated lymphocyte adhesion to VCAM-1, MAdCAM-1, and fibronectin in vitro and in vivo

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

DATK32 antibody is specific for a combinatorial determinate of integrin α4β7complex. Integrin α4β7 is composed of a 150 kD (α4 or CD49d) and a 130 kD (β7) heterodimer, also known as CD49d/β7 or LPAM-1. Belonging to the Ig superfamily, it is found on the majority of peripheral lymphocytes and subsets of thymocytes and bone marrow cells (including mast cell progenitors). Integrin α4β7 binds its ligands, VCAM-1 (CD106), MAdCAM-1 and fibronectin, and plays an important role in lymphocytes adhesion and the direction of migration of blood lymphocytes to the intestine and associated lymphoid tissues.
