2.10. Determination of fibrinolytic activity
Two assays, the fibrin plate assay and nattokinase activity, were
performed to determine the fibrinolytic activity of the fermented
red beans according to Astrup and Müllertz (1952) and Deepak
et al. (2008), respectively. One unit of fibrinolytic activity (FU) is
defined as the amount of enzyme required to produce an increase
in absorbance equal to 0.01 in 1 min at 275 nm (Deepak et al.,
2008).
