A potent, cell-permeable, reversible, and ATP-competitive Src family kinase inhibitor. Inhibits Src (IC 50 = 280 nM) as well as closely related kinases such as Fyn (IC 50 = 170 nM) and Yes (IC 50 = 20 nM) and Lyn (IC 50 = 130 nM).

A hydroxamate-based inhibitor of collagenase, gelatinase, and TACE (TNF-&#945 converting enzyme/ADAM17 IC 50 = 100 nM). Blocks spontaneous and PMA-induced release of TNF-&#945 in transfected COS 7 cells.

Universal Food pathogen ID Membranes are substrate-carrying membranes used for rapid identification and differentiation of food pathogens through characteristic color reactions by placing on the agar surface post-incubation. The membranes contain
