Pw. Genest et al., CONTINUOUS PURIFICATION OF PORCINE LIPASE BY ROTATING ANNULAR SIZE-EXCLUSION CHROMATOGRAPHY, Applied biochemistry and biotechnology, 73(2-3), 1998, pp. 215-230
Crude porcine lipase (triacylglycerol lipase, EC 3.1.1.3) was purified
in a single-stage chromatographic process. The purification was accom
plished in a batch, as well as in a continuous system. Two types of si
ze-exclusion packing materials (Sephadex and Sephacryl) were used. The
average x-fold increase in purity, and the average recovered activity
in the batch Sephadex and Sephacryl experiments were 13.6 and 89.7%,
and 34.2 and 98.8%, respectively. The average x-fold increase in purit
y and the average activity recovered in the continuous Sephadex and Se
phacryl experiments were 27.1 and 82.5% and 16.2 and 89%, respectively
. Flow visualization experiments were carried out by tagging the prote
in to be separated with a fluorescent dye The results from these exper
iments are also reported in this article.
