DESCRIPTION

Used for the quantitative determination of Anti-Tirzepatide (LY3298176) Human IgG concentration in serum and plasma.

PRINCIPLE OF THE ASSAY

This assay employs the quantitative indirect enzyme immunoassay technique. Tirzepatide has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any Anti-Tirzepatide (LY3298176) Human IgG present is bound by the immobilized protein. After washing away any unbound substances, a HRP conjugated probe 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 proportion to the amount of Anti-Tirzepatide (LY3298176) Human IgG 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): <10% Three samples of known concentration were tested sixteen times on one plate to assess intra-assay precision. Inter-Assay Precision (Precision between assays): <15% Three samples of known concentration were tested in twenty four separate assays to assess inter-assay precision.

RECOVERY

The recovery of Anti-Tirzepatide (LY3298176) Human IgG 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	100	90-107
	1:20	97	90-115

LINEARITY

To assess the linearity of the assay, human serum samples were spiked with high concentrations of Anti-Tirzepatide (LY3298176) Human IgG 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	103	96-108
	1:4	101	98-104
	1:8	102	99-104
	1:16	110	94-119
