One-step, inexpensive high yield strategy for Candida antarctica lipase A isolation using hydroxyapatite
Lipase A from Candida antarctica (CAL A) was purified to apparent homogeneity in a single step using hydroxyapatite (HAP) chromatography. CAL A bound to HAP was eluted with 10 mM Na-phosphate buffer, pH 7.0 containing 0.5% Triton X-100. The protocol resulted in a 3.74-fold purification with 94.7% fi...
