生物活性

(±)-Catechin (rel-Cianidanol) This is a green tea polyester. Catechin possesses anti-cancer activity, which has led to its demise. (±)-Catechin 具有两种forms (+)-Catechin and its reflection body (-)-Catechin. (+)-Catechin inhibitory environment-1 (COX-1) IC₅₀ 为 1.4 μM. (-)-Catechin has the effect of promoting hBM-MSC adipose cell differentiation, increasing adipose tissue, and PPARγ horizontal. (±)-Catechin has anti-diabetic, anti-hypertrophic, anti-diabetic, anti-cardiovascular, anti-infective, and liver-protecting effects.

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.
