Recombinant Antibody
Specificity
FIB27 binds specifically to both human and mouse integrin beta-7 at epitope region Dl on which is involved in all a4b7-mediated adhesion events. Does not compete with DAKT32 for binding. FIB27 blocks LS722-induced TK1 cell aggregation (mAb LS722 is an activating anti-a4B7 antibody and induces aggregation via an a4B7-dependent pathway). Integrin beta-7 is one subunit is a heterodimer which makes up an intergin molecule. In the mouse beta-7 is selectively found on the majority of mature lymphocytes, whereas a small subpopulation of thymocytes and bone marrow cells express beta-7. Beta-7 is also expressed in variable amounts in CD4 T memory cells. Integrin molecules mediate cell-cell and cell- extracellular matrix adhesion and are involved in lymphocyte homing, leukocyte recruitment to inflammatory sites, myogenesis, hemopoiesis, and melanoma metastasis.

Immunogen
FIB27 was prepared by immunizing rats with TK1 cells.
Application Notes
FIB27 can be used for FC, IP and can block TKI cell aggregation and beta-7 intergrin- mediated cell adhesion.
