This IRS-1 (phospho Ser307) Cell Based ELISA Kit allows for the detection of IRS-1 (phospho Ser307) and the effects that certain stimulation conditions have on IRS-1 (phospho Ser307) expression in different cell lines. Qualitative determination of IRS-1 (phospho Ser307) concentration is achieved by an indirect ELISA format. In essence, IRS-1 (phospho Ser307) is captured by Anti-IRS-1 (phospho Ser307) Antibodies while Dye 1-conjugated and Dye 2-conjugated secondary antibodies bind the Fc region of the primary antibody. Through this binding, the dye conjugated to the secondary antibody can emit light at a certain wavelength given proper excitation, hence allowing for a fluorometric detection method. A monoclonal antibody specific for human GAPDH is included to serve as an internal positive control in normalizing the target RFU values. Anti-IRS-1 Antibody is also included for normalization purposes. The RFU values obtained for the non-phosphorylated target can be used to normalize the RFU value for the phosphorylated target.
