The PathScan® Phospho-eIF2α (Ser51) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of eIF2α phosphorylated at Ser51. A eIF2α rabbit antibody has been coated onto the microwells. After incubation with cell lysates, eIF2α protein is captured by the coated antibody. Following extensive washing, a phospho-eIF2α (Ser51) mouse detection antibody is added to detect captured phospho-eIF2α protein. Anti-mouse IgG, HRP-linked antibody is then used to recognize the bound mouse detection antibody. HRP substrate TMB is added to develop color. The magnitude of the absorbance for this developed color is proportional to the quantity of eIF2α phosphorylated at Ser51.
