A method for determining the biological activity of a di-fibrotide is disclosed, the method comprising contacting a substrate specific for plasmin with a measurable product through the reaction of di-fibrotide, mammalian euglobulin, ; And b) measuring the amount of the product formed continuously to measure the biological activity of the di-fibrotide. A liquid dipeptide formulation having a defined biological activity, in particular having a biological activity of 25 to 35 IU / mg, preferably 27.5 to 32.5 IU / mg, more preferably 28 to 32 IU / mg dibutylate Preferably an aqueous solution) is also disclosed. |
