Technical Support

Calcium oxide (CaO) acts as a heterogeneous base catalyst. Calcium oxide can be extracted not only from waste materials such as oyster shells, eggshells and crab shells, but also exhibits tolerance to low to moderate oil quality, free fatty acid and water content in raw materials. Calcium oxide can be used in biodiesel production, where it effectively catalyzes the transesterification of vegetable oils or animal fats to produce alkyl esters.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
