Description
Human Phospho-eIF-2A (S52) and Total eIF-2A PharmaGenie ELISA Kit
Assay Genie Phospho-eIF-2A (S52) and Total eIF-2A 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 eIF-2A 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-eIF-2A and total eIF-2A. An anti-pan eIF-2A antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and eIF-2A present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-eIF-2A (S52) antibody is used to detect phosphorylated eIF-2A or rabbit anti-eIF-2A antibody is used to detect pan eIF-2A. After washing away unbound antibody, HRP-conjugated streptavidin or 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 eIF-2A (S52) or pan eIF-2A bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
