#Unit 13. Methods in Biology

To measure the activity of a promoter, one can link it to a reporter gene, such as the genes encoding b-galactosidase, CAT, or luciferase, and let 

the easily assayed reporter gene products indicate the activity of the promoter.

When blood platelets are activated during a clotting reaction, they release high concentrations of ATP and Ca2+ along with serine/threonine kinases. Phosphorylated C3b is less susceptible to proteolytic degradation than its unphosphorylated form
