* Alternatively, this assay can be run over two days, which requires 2 hours 30 mins (day 1) and 4 hours (day 2).
R&D Systems Cell-Based ELISAs simultaneously measure the levels of two proteins in the same microplate well in whole, fixed cells, eliminating the need for lysate preparation. These simple, sensitive assays can be used with both adherent and non-adherent cells to analyze protein phosphorylation or assess total protein levels.
Cell-Based ELISA Kits are available in two formats: phospho-protein kits contain antibodies to measure both the phosphorylated and the total protein, while total protein kits contain antibodies to the protein of interest and a second housekeeping protein. These two proteins are simultaneously detected in the same microplate well, allowing signals derived from the target protein to be normalized to that of the second protein. This permits corrections for well-to-well variation and allows target protein levels to be accurately assessed and compared across multiple samples. This Phospho-
