Detects the dual phosphorylated forms of ERK1 at Thr202 and Tyr204 and ERK2 at Thr185 and Tyr187. This activation occurs as a result of treatment with a large variety of stimuli including mitogens, cytokines, and growth factors. Although this kit was designed for human samples, it cross-reacts with mouse and rat.

|---|---|---|---|
 Jurkat cells were treated with 100 ng/ml PMA for 10 min and cell lysates were prepared. Cell lysate prepared with Cell Lysis Buffer was either boiled for 5 min, treated with Sample Treatment Buffer, or not treated. Cell lysate was also prepared using Denaturing Cell Lysis Buffer. Samples were analyzed with the ERK1/2 and the PhosphoDetect™ ERK (Thr<Sup>185</sup>/Tyr<sup>187</sup>) ELISA Kits.  The sensitivity of this ELISA was compared to immunoblotting using known quantities of ERK1/2 Phospho-Thr<sup>185</sup>/Tyr<sup>187</sup>. The data shows that the sensitivity of the ELISA is approximately 4X greater than that of immunoblotting. The bands shown in the immunoblotting were developed using rabbit anti-ERK1/2 Phospho-Thr<sup>185</sup>/Tyr<sup>187</sup> and an alkaline phosphatase conjugated anti-rabbit IgG followed by chemiluminescent detection.  Natural ERK1/2 Phospho-Thr<sup>185</sup>/Tyr<sup>187</sup> from PMA-treated Jurkat cell lysates was serially diluted in Standard Diluent Buffer. The absorbance of each dilution was plotted against the ERK1/2 Phospho-Thr<sup>185</sup>/Tyr<sup>187</sup> standard curve. Parallelism is demonstrated in the figure above and indicates that the standard accurately reflects natural ERK1/2 Phospho-Thr<sup>185</sup>/Tyr<sup>187</sup> content in samples. |
