WebDec 6, 2024 · Use a primary and secondary reporter vector transiently transfected into your favorite mammalian cell line. The primary reporter is commonly used as a marker for a gene, promoter, or response element of interest. The secondary reporter drives a steady level of expression of a different marker. WebIf you’re doing a dual reporter assay, then you will clone your other reporter into a separate plasmid. Step 3: Cotransfect your experimental cells with your plasmid. Step 4: After an incubation period of 24-48 hours, remove your media and lyse your cells. Step 5: Add the buffer containing luciferin to the lysate.
