DESCRIPTION

Used for the quantitative determination of Anti-Rosopatamab concentration in serum and plasma.

PRINCIPLE OF THE ASSAY

This assay employs the quantitative sandwich enzyme immunoassay technique. Rosopatamab has been pre-coated onto a microplate. Samples or standards are pipetted into microwells and Anti-Rosopatamab will be captured by immobilized Rosopatamab. After washing away any unbound substances, a biotin-labeled Rosopatamab is added to the wells. 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 proportion to the amount of Anti-Rosopatamab 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-Rosopatamab 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	81-117
	1:20	89	80-120

LINEARITY

To assess the linearity of the assay, human serum samples were spiked with high concentrations of Anti-Rosopatamab 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	100	95-110
	1:4	104	98-110
	1:8	105	89-116
	1:16	104	87-114
