Fig. 1. Gel filtration and ion-exchange chromatography plots. (a) Shows the gel
filtration chromatography on Sephadex G-200 when the column was equilibrated
with sodium acetate buffer at pH 6. The protein of interest eluted in the unbound
samples. (b) The non-retained fraction from Sephadex-200 was loaded to ionexchange
chromatography on DEAE-Sepahdex. Column was eluted with linear salt
gradient in the same buffer. The enzyme eluted as a single peak.
