Human LDL Receptor ELISA Kit is a sandwich (quantitative) Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human LDL Receptor in tissue homogenates, cell lysates or other biological fluids.

Assay-Typ

Sandwich (quantitative)

Assay-Prinzip

Human LDL Receptor ELISA Kit employs the Sandwich Enzyme Immunoassay (ELISA) technique for the quantitative measurement of human LDL Receptor in human. An antibody specific for LDL Receptor has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the LDL Receptor present in each sample is bound to the wells by the immobilized antibody. Following incubation, the wells are washed and then incubated with Biotinylated Anti-LDL Receptor Antibody, which binds the captured LDL Receptor present in each well. Following incubation, unbound biotinylated detection antibody is removed by washing, and Avidin conjugated to Horseradish Peroxidase (Avidin-HRP) is added to the wells and the microtiter plate is incubated. Following incubation and washing, TMB substrate solution is used to visualize the HRP enzymatic reaction by catalysis to produce a blue-coloured product that changes to yellow after addition of acidic stop solution. The density of yellow is proportional to the amount of LDL Receptor captured in each well. The concentration of LDL Receptor can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.
