WebHow do Luciferase Assays Work? Firefly luciferase assays ( SCT151, SCT154, LUC1, LUCASSY-RO) are designed for simple and efficient quantitation of firefly luciferase reporter enzyme activity from cultured cells with high sensitivity and linearity. WebHow the Bradford Protein Assay Works The Bradford protein assay is a time-tested colorimetric assay. When the Bradford reagent (acidified Coomassie Brilliant Blue G-250) binds to proteins, the dye undergoes a color change in the visible spectrum, with the absorbance maximum moving from 470 to 595 nm.
