Introduction:
Golimumab (CNTO 148) is a human monoclonal antibody which is used as an immunosuppressive drug and marketed under the brand name Simponi. Golimumab targets tumor necrosis factor alpha (TNF-alpha), a proinflammatory molecule and hence is a TNF inhibitor. Profound reduction in C-reactive protein (CRP) levels, interleukin (IL)-6, intercellaular adhesion molecules (ICAM)-1, matrix metalloproteinase (MMP)-3, and vascular endothelial growth factor (VEGF) demonstrates golimumab as an effective modulator of inflammatory markers and bone metabolism.
Intended Use:
The KRIBIOLISA™ Golimumab ELISA is used as an analytical tool for quantitative determination of Golimumab in serum, plasma and cell culture supernatant.
Principle:
The method employs the quantitative sandwich enzyme immunoassay technique. Antibodies to Golimumab are pre-coated onto microwells. Samples and standards are pipetted into microwells and human Golimumab present in the sample are bound by the capture antibody. Then, a HRP (horseradish peroxidase) conjugated anti-Golimumab antibody is pipetted and incubated. After washing microwells in order to remove any non-specific binding, the ready to use substrate solution (TMB) is added to microwells and color develops proportionally to the amount of Golimumab in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
