BIOPHEN® CS-61(44) — specific chromogenic substrate for Urokinase (uPA). Equivalent to Chromogenix S-2444. 1 × 25 mg lyophilized. Research use.

CS-61(44) is cleaved by urokinase-type plasminogen activator (uPA), releasing pNA at 405 nm. Also shows activity with tPA and plasmin. Used in fibrinolysis research, uPA activity characterization, plasminogen activator inhibitor (PAI-1) functional studies, and broad fibrinolytic system research.

• Urokinase (uPA) active substrate — also reactive with tPA and plasmin
• Equivalent to Chromogenix S-2444
• For fibrinolysis and plasminogen activator research
• 1 × 25 mg lyophilized
