Description
Principle of the Assay: The Human Apolipoprotein E ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human Apolipoprotein E in Cell Culture Supernates, Serum, Plasma, Saliva, Urine, Human Milk. This assay employs an antibody specific for Human Apolipoprotein E coated on a 96-well plate. Standards and samples are pipetted into the wells and Apolipoprotein E present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human Apolipoprotein E antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin 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 Apolipoprotein E bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.
