Table 1. Purification summary of xylarinase from Xylaria curta.
Figure 2. Determination of homogeneity, molecular mass and fibrinolytic activity of xylarinase. (a) SDS-PAGE analysis of purified xylarinase. Xylarinase resolved from MPLC, Sephacryl S-300 column was electrophoresed on 10% SDS gel. The gels were stained using silver staining method. (b) Determination of molecular weight by MALDI-TOF method.
