The UPSTATE® colorimetric STAR (Signal Transduction Assay Reaction) ELISA kit is a solid phase sandwich enzyme linked immunosorbent assay that provides a fast, sensitive method to detect specific levels of signaling targets in whole cell extracts. The EGFR plate is coated with a specific mouse monoclonal EGFR capture antibody. Sample lysate or the standard included in the kit are incubated in the microwells allowing EGFR antigen to be captured. The plate is then washed to remove any unbound non-specific material. A specific rabbit anti-phospho- EGFR antibody is added to detect the captured phosphorylater EGFR (Tyr1068) on the plate well. The unbound detection antibody is washed away followed by incubation with an HRP-conjugated anti-rabbit antibody. After the addition of TMB substrate and...Read more
