Cayman's STEP Reporter Assays (Luminescence) consist of a 96-well plate pre-coated with a transfection complex consisting of the gene for the protein target of interest (i.e. an assay specific target protein), a SEAP reporter construct, and, in some cases, other genes needed to make the assay function with high fidelity. The plates are provide sealed and ready to use - all you need to do is add your cells. Transfection occurs overnight; cells can be tested the next day. The SEAP reporter is secreted into the media, so cellular responses can be followed over time. The kits are easily adapted to high throughput screening.
