My solution of Product L2157, Laccase from Rhus vernicifera, isn't clear. Is this normal?
1 answer-
Yes. L2157 is a crude acetone powder, and can contain other proteins, enzymes, and cellular debris. A suspension may be prepared in 100 mM potassium phosphate buffer, pH 6.5, by homogenization with a hand-held homogenizer for 10 minutes. This preparation may then be centrifuged; the laccase activity will be present in the supernatant.
