Guselkumab ELISA Kit

Catalog No.

KDJ63102

Description

PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human IL23A has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Guselkumab in the sample competitively binds to the pre-coated protein with biotin-labeled Guselkumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Guselkumab bound in the initial step. The color development is stopped and the intensity of the color is measured.

Applications

Used for the quantitative determination of Guselkumab concentration in serum and plasma.

Precision

Intra-Assay Precision (Precision within an assay): <20%

Three samples of known concentration were tested sixteen times on one plate to assess intra-assay precision.

Inter-Assay Precision (Precision between assays): <20%

Three samples of known concentration were tested in twenty four separate assays to assess inter-assay precision.
