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.

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Concentration _(start) × Volume _(start) = Concentration _(final) × Volume _(final)

This equation is commonly abbreviated as: C₁V₁ = C₂V₂

Specific Activity (Unit/mg) = 10⁶ ÷ Biological Activity (ED₅₀)
