Phospho-SHP-1 (S591) and Total SHP-1 ELISA Kit

Product details

Phospho-SHP-1 (S591) and Total SHP-1 ELISA Kit (ab279924) is a very rapid, convenient, and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated SHP-1 protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.

This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-SHP-1 and total SHP-1. An anti-pan SHP-1 antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and SHP-1 present in a sample is bound to the wells by the immobilized antibody and the wells are washed. In select wells, rabbit anti-phospho SHP-1 (S591) antibody is added to detect phosphorylated SHP-1. In the remaining wells, biotinylated anti-pan-SHP-1 antibody is used to detect pan SHP-1. After washing away unbound antibody, HRP-conjugated anti-rabbit IgG or HRP-Streptavidin is pipetted into the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of SHP-1 (S591) or pan SHP-1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
