As a leading brand of Korainbio, Bioassay Technology Laboratory (BT Lab) offers a variety of cost-effective ELISA kits and sets to measure cytokines, chemokines, and soluble biomarkers consistently and reliably. Sandwich kit and Competitive that provide the core reagents our selection of ELISA products meets thedemand of ELISA beginners to experts alike at a very economical price.
Sandwich kits are fully validated and ready-to-use, containing 96- well strip plates pre-coated with capture antibody to detect sample antigen.
In a competitive ELISA assay, sample antigen and labeled antigen compete for capture antibody binding. The more target protein there is in the sample, the less labeled antigen will be captured and the weaker the signal.
Qualitative results provide a simple positive or negative result for a sample. In quantitative ELISA, the optical density (OD) of the sample is compared to a standard curve, which is typically a serial dilution of a known-concentration solution of the target molecule.
