 Description
Frequently Asked Questions Live Chat and Frequently Asked Questions are available for this Product.
Application Yeast cells are difficult to disrupt because the cell walls may form capsules or resistant spores. DNA can be extracted from yeast by using lysing enzymes such as lyticase, chitinase, zymolase, and gluculase to induce partial spheroplast formation; spheroplasts are subsequently lysed to release DNA. Lyticase is preferred to digest cell walls of yeast and generate spheroplasts from fungi for transformation.
Reported to be useful for lysis of Ashbya, Candida, Debaryomyces, Eremothecium, Endomyces, Hansenula, Hanseniaspora, Kloeckera, Kluyveromyces, Lipomyces, Metschikowia, Pichia, Pullularia, Torulopsis, Saccharomyces, Saccharomycopsis, Saccharomycodes, and Schwanniomyces species.
Biochem/physiol Actions Lyticase hydrolyzes poly-β(1→3)-glucose such as yeast cell wall glucan.
