Integrin activation assay

NettetThe activated integrin β1 antibody, which binds to β1 only when it is in the active conformation, was used for these assays. We found that there was little interaction between activated integrin β1 and p-FAK in untreated cells, while IGFBP2 administration to HCC cells induced a time-dependent interaction between the two proteins ( Figure … Nettet1. nov. 2010 · Integrin β1 is a common mediator of fibroblast attachment to collagen type I and fibronectin ( Lafrenie and Yamada, 1996; Gabbiani, 2003 ), suggesting that expression of integrin β1 by fibroblasts has a key role in cutaneous tissue repair. However, this hypothesis has not yet been tested.
