The IRS1 [pS312] Human ELISA kit is designed to detect and quantify the level of IRS1 [pS312] protein phosphorylated at serine residue 312. This assay is intended for the detection of IRS1 [pS312] from human, mouse and rat cell extracts using 96-well plates and a microplate reader.
• Easy to run
• More sensitive than Westerns
• Convenient precoated, removable 8-well strips
Easy-to-Run Sandwich ELISA
A monoclonal capture antibody specific for IRS1 has been coated onto the wells of the 96-well plate provided. During the first incubation, standards of known IRS1 [pS312] content and unknown samples are pipetted into the wells and the IRS1 antigen binds to the immobilized (capture) antibody. After washing, a rabbit antibody specific for IRS1 phosphorylated at serine 312 is added to the wells. During the second incubation, this antibody serves as a detection antibody by binding to the immobilized IRS1 protein captured during the first incubation. After washing, a horseradish peroxidase labeled anti-rabbit IgG is added. This binds to the detection antibody to complete the four member sandwich. After a third incubation and washing to remove all the unbound enzyme, a substrate solution (TMB) is added, which is acted upon by the bound enzyme to produce color. The intensity of this colored product is directly proportional to the concentration of IRS1 [pS312] present in the original specimen and the optical density can be read on a standard microplate reader. The total assay incubation time is only 4 hours.
Detect Low Expressing Proteins and Use Less Sample
ELISA kits designed to measure intracellular signaling targets are 2–10X more sensitive than Western blotting. The improved sensitivity enables you to detect low-expressing proteins that otherwise may not be distinguishable from background. In addition, the amount of sample needed to run the assay is less than what is needed for Western blots.

Convenient Kit Format
The kit comes with a capture antibody precoated to the plate, eliminating an overnight coating process. The plates are machine coated to provide low variability well-to-well. Furthermore, the plate comes as removable 8-well strips allowing you to run as few samples as you want. In addition, the standards provided in the kit can be used to obtain quantitative results from the standard curve and/or can be used as a positive control.
Each ELISA kit is validated for sensitivity, specificity, precision, and lot-to-lot consistency. See protocol insert for more information on validation.
