Description

Human Phospho-Chk1 (S280) and Total Chk1 PharmaGenie ELISA Kit (SBRS1775)

Assay Genie Phospho-Chk1 (Ser280) and Total Chk1 ELISA kit 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 Chk1 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-Chk1 and total Chk1. An anti-pan Chk1 antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and Chk1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and rabbit anti-Chk1 (Ser280) antibody is used to detect phosphorylated Chk1 or rabbit anti-Chk1 antibody is used to detect pan Chk1. After washing away unbound antibody, HRP-conjugated anti-rabbit IgG is pipetted to 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 Chk1 (Ser280) or pan Chk1 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
