FAQs

Do you also offer a ready-to use rat liver S9-Mix?

Yes. MUTAZYME^™ consists of lyophilized rat liver S9 that already includes NADP, D-glucose-6-phosphate, MgCl2, KCl in pH 7.4 sodium phosphate buffer. After reconstitution the resultant S9 Mix may be directly used in the standard plate incorporation assays or liquid fluctuation tests.

We observe lot-specific toxicity using S9 for some of our cell assays. Can you advise?

Experience showed that Mutazyme^™ is less toxic to certain cells than regular S9 preparations.
