DESCRIPTION

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

PRINCIPLE OF THE ASSAY

This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human IL17A has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Netakimab in the sample competitively binds to the pre-coated protein with biotin-labeled Netakimab. 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 Netakimab bound in the initial step. The color development is stopped and the intensity of the color is measured.

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.

RECOVERY

The recovery of Netakimab spiked to three different levels in human serum samples throughout the range of the assay was evaluated.

Sample	Dilution factor	Average (%)	Range (%)
Human serum (n=3)	1:10	96	83-107
	1:20	91	81-104

LINEARITY

To assess the linearity of the assay, human serum samples were spiked with high concentrations of Netakimab and diluted with the Standard Diluent to produce samples with values within the dynamic range of the assay.

Sample	Dilution factor	Average (%)	Range (%)
Human serum (n=3)	1:2	102	97-107
	1:4	112	111-112
	1:8	107	103-112
	1:16	108	102-116
