Human interferon beta bioluminescent ELISA kit

LumiKine™ hIFN-β is a bioluminescent ELISA kit designed to quantify the levels of human interferon-beta (hIFN-β) in cell culture supernatant, serum and plasma samples.

This kit uses optimized matched pairs of monoclonal capture and detection antibodies to achieve sensitive and accurate measurement of the cytokine. The detection antibody is labeled with biotin to allow subsequent binding to streptavidin-Lucia, streptavidin conjugated to Lucia luciferase, a secreted reporter enzyme.
Levels of hIFN‑β are determined by measuring the luminescence produced by Lucia luciferase after hydrolysis of its substrate, coelenterazine. This substrate is provided in QUANTI-Luc™, a reagent that allows immediate reading of the luminescence.

LumiKine principle

Principle

The monoclonal hIFN-β Capture Antibody is coated onto the wells of a white immuno 96-well plate.

Samples and the hIFN-β Standard are pipetted into these wells, followed by the addition of the monoclonal Biotinylated Antibody (detection antibody).

During the first incubation, the hIFN-β antigen binds to the immobilized hIFN-β Capture Antibody on one site, and during the second incubation, to the Biotinylated Antibody on a second site.

After removal of the excess detection antibody, Streptavidin-Lucia is added. This streptavidin conjugate binds to the Biotinylated Antibody.

After a short third incubation and washing to remove all the unbound Lucia luciferase, QUANTI-Luc™, a solution that contains the substrate of Lucia luciferase, is added. No further incubation is required. The bioluminescent signal is emitted instantaneously and measured in Relative Light Units (RLU) by a luminometer. The intensity of this signal is directly proportional to the concentration of hIFN-β present in the samples.
