– based on sandwich principle
the drg papp-a elisa kit is a solid phase enzyme-linked immunosorbent assay (elisa) based on the sandwich principle.
the microtiterwells are coated with a polyclonal anti papp-a antibody. an aliquot of donor sample containing endogenous papp-a is incubated in the coated well with assay buffer. after incubation the unbound material is washed off. in the second incubation step a sandwich complex is formed with a polyclonal anti papp-a antibody peroxidase conjugate. having added the substrate solution, the intensity of color developed is proportional to the concentration of papp-a in the donor sample.
