By Amanda Hurley | February 20, 2019

Radioactivity is still the most sensitive detection mechanism for many macromolecules and enzymatic activities. In graduate school, I performed countless radioactive kinase assays, watching the radioactive gamma 32P of ATP get transferred to my autophosphorylating receptor of interest, and then separating my protein from free hot ATP on a gel. The gel is dried, covered…
