Invitrogen IL-2 Human ELISA Kit, High Sensitivity, 96 Tests

The Human High Sensitivity Interleukin 2 (HS IL-2) ELISA quantitates Hu HS IL-2 in human serum, plasma, buffered solution, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu HS IL-2.
Principle of the method
The Human HS IL-2 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. A special amplification reagent step is added to achieve the high sensitivity capability. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
