Assay Principle
The principle of the double antibody sandwich ELISA is represented in Figure 1. In this assay the GTP-binding nuclear protein (RAN) present in samples reacts with the anti-RAN antibodies which have been adsorbed to the surface of polystyrene microtiter wells. After the removal of unbound proteins by washing, the Detection Antibody, biotin conjugated anti-RAN, is added and complexes are formed. Following a wash step, the horseradish peroxidase (HRP) conjugated Streptavidin is added and complexes are formed. After another washing step, the complexes are 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 RAN in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of RAN in the test sample. The quantity of RAN in the test sample can be interpolated from the standard curve constructed from the standards, and corrected for sample dilution.
SPECIMEN COLLECTION AND HANDLING
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.
