Assay Principle

In this Human Kappa ELISA assay the Kappa present in samples reacts with the anti-Kappa antibodies which have been adsorbed to the surface of polystyrene microtitre wells. After the removal of unbound proteins by washing, anti-Kappa antibodies conjugated with horseradish peroxidase (HRP), are added. These enzyme-labeled antibodies form complexes with the previously bound Kappa. Following another washing step, the enzyme bound to the immunosorbent is assayed by the addition of a chromogenic substrate, 3,3’,5,5’-tetramethylbenzidine (TMB). The quantity of bound enzyme varies directly with the concentration of Kappa in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of Kappa in the test sample. The quantity of Kappa in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.

Blood should be collected by venipuncture. The serum should be separated from the cells after clot formation by centrifugation. For plasma samples, blood should be collected into a container with an anticoagulant and then centrifuged. Care should be taken to minimize hemolysis, excessive hemolysis can impact your results. Assay immediately or aliquot and store samples at -20°C. Avoid repeated freeze thaw cycles.
