Specifications

Zymolyase, produced by a submerged culture of Arthrobacter luteus (1), is an enzyme preparation which effectively lyses cell walls of viable yeast cells. An essential enzyme responsible for lysis of viable yeast cells in this preparation is b-1, 3-glucan laminaripentaohydrolase. It hydrolyzes linear glucose polymers with b-1,3-linkages and releases laminaripentaose specifically as the main and minimum product unit (4,5,10,11). This lytic activity releases spheroplasts and protoplasts in the preparation of yeast DNA prior to restriction enzyme digestion and Southern Blot analysis. The extent of lysis of yeast cells by Zymolyase varies with yeast strain, growth stage of yeast and cultural condition (6-8). Further information related to Zymolyase is obtained in the references below.

Z1001: Zymolyase 20T Concentrate 50mg/ml, 0.1M Sorbitol
Zymolyase 20T shows 20u/mg of the lytic activity, defined after, toward brewer's yeast cells (Saccharomyces cerevisiae, resting stage) or toward yeast cells of Saccharomyces cerevisiae IFO 0565 cultured statically in malt extract medium (Malt extract 2g, peptone 0.5g, water 100ml) at 20ºC for 34 hours.
Z1004 Zymolyase 100T
Z1005: Zymolyase 100T Concentrate 10mg/ml, 0.1M Sorbitol
Zymolyase 100T, further purified, whose specific activity is 100u/mg.
Note Zymolyase100T is less soluble than 20T and may not be completely dissolved in buffers. If this is the case use as a suspension.
CAS Number37340-57-1
* Lyticase is similar but testing has shown that Zymolyase exhibits greater lytic activity.
