Hello everyone.

We are using thrombin from bovine plasma (T4648-1KU, sigma). ¿How can we make a stock of 100 U/ml thrombin (0.1% BSA solution)? ¿Should we weigh the powder and reconstitute it according to our desired concentration?

The website says that 10mg/ml should be fine at -20ºC, but again we only have the data of 1000 U.

Thank you for your help!
