How stable are solutions of Product L2157, Laccase from Rhus vernicifera?
Solutions should be prepared fresh, directly before use, as they are not stable as stock solutions.
My solution of Product L2157, Laccase from Rhus vernicifera, isn't clear. Is this normal?
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.
What is the molecular weight (MW) of Product L2157, Laccase from Rhus vernicifera?
Spira-Solomon and Solomon, J. Am. Chem. Soc., 109, 6421-6432 (1987) reports estimated molecular weights of 52 kDa (laccase 1), 55 kDa (laccase 2), and 70 kDa (laccase 3), as determined by gel filtration.
What is the pH optimum of Product L2157, Laccase from Rhus vernicifera?
Our own assay is performed at pH 6.5. One publication (Casella et al., J. Inorg. Biochem., 100, 2127-2139 (2006)) gives pH 6.5 as another value for the laccase from this species, with a range for enzyme activity of 4.3 to 9.
What is the temperature optimum of Product L2157, Laccase from Rhus vernicifera?
Our own assay is performed at 30°C. One publication (Casella et al., J. Inorg. Biochem., 100, 2127-2139 (2006)) gives 25°C as another value for the same enzyme from the same species.
