Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How do I solubilize Product L2524, Lyticase?
The quality control enzymatic assay protocol for Lyticase uses cold deionized water to make a solution at 500 units/mL.
How can I store Product L2524, Lyticase, once reconstituted?
When lyticase is reconstituted and stored, it may be stable for no more than 4-6 hours before serious loss of activity is observed. It is suggested that fresh solutions be prepared for use.
How canProduct L2524, Lyticase, be used to make yeast spheroplasts?
The use of lyticase in combination with chitinase and glucuronidase in the preparation of spheroplasts from C. albicans has been described in the following reference:Calvert, C.M., and Sanders, D., "Inositol Trisphosphate-dependent and -independent Ca2+ Mobilization Pathways at the Vacuolar Membrane of Candida albicans."J. Biol. Chem.270, 7272-7280 (1995).
