Description of GGACK (H-Glu-Gly-Arg-chloromethylketone)

GGACK (H-Glu-Gly-Arg-chloromethylketone) is an irreversible serine protease inhibitor. GGACK can inhibit urokinase-type plasminogen activator (uPA) and block the plasminogen activation process. GGACK can be used for research related to cancer and coagulation-related diseases[1].

GGACK (10-100nM) had been used to treat PMA-stimulated U-937 leukemia cells for 30 minutes to induce high expression of uPAR, after which fluorescently labeled HMW-uPA was added. GGACK competitively inhibited the binding of HMW-uPA to the cell surface uPAR receptors[2].

Protocol of GGACK (H-Glu-Gly-Arg-chloromethylketone)

Cell experiment [1]:

Cell lines

U-937 cells (human monocyte-like leukemia cell line)

Preparation Method

Phorbol 12-myristate-13-acetate (PMA)-stimulated U-937 cells were used. For the competition flow cytometry assay, cells were pre-incubated on ice for 30 minutes with 10nM or 100nM of either GGACK-inactivated HMW-uPA (i-uPA) or a test compound. Subsequently, 1nM of Alexa Fluor 488-labeled active HMW-uPA was added and incubated with the cells for 30 minutes on ice. The samples were then washed, fixed, and analyzed by flow cytometry.

Reaction Conditions

10nM or 100nM; 30min pre-incubation on ice.

Applications

GGACK-inactivated HMW-uPA (i-uPA) potently antagonized the binding of Alexa Fluor 488-labeled active HMW-uPA to cell surface urokinase-type plasminogen activator receptors (uPAR). GGACK inhibited the fluorescent signal, demonstrating its strong efficacy as a competitive antagonist in the uPA:uPAR binding assay.
