Urokinase type plasminogen activator u pa

Manufactured by Merck Group
Sourced in United States

Urokinase-type plasminogen activator (u-PA) is a laboratory reagent used in research applications. It is a serine protease that catalyzes the conversion of plasminogen to plasmin, a key enzyme involved in fibrinolysis and extracellular matrix remodeling.

Human fibrinogen, thrombin, FXa, FXIIIa, urokinase-type plasminogen activator (u-PA), trizma base, and trizma HCl were purchased from Sigma-Aldrich (St. Louis, MO, USA). Paranitroaniline chromogenic substrates were obtained from Chromogenix (Milan, Italy). Alexa Fluor 488-conjugated fibrinogen was purchased from Invitrogen (Eugene, OR, USA). Other reagents used were of analytical grade and purchased from commercial sources.

Plasmin Activity Assay with GAPDH

Check if the same lab product or an alternative is used in the 5 most similar protocols
Briefly, 20 μg of recombinant GAPDH proteins was incubated with 150 nM human plasminogen, 0.5 U urokinase-type plasminogen activator (uPA; Sigma-Aldrich), and 0.2 mM chromogenic substrate of plasmin (MyBioSource, San Diego, CA, USA). Increase in plasmin activity was assessed at 30-min intervals by measuring absorbance at 405 nm for 3 h. In inhibition tests, 10 mM EACA was added.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
