Precision
Intra-Assay Precision (Precision within an assay) Each control was tested multiple times in one CD21 assay.
Inter-Assay Precision (Precision between assays) Replicates of each CD21 control were tested in multiple assays performed by at least three technicians using two lots of reagents for human CD21.

Recovery for Simple Plex Human CD21 Cartridge
Recovery was not necessary as human CD21 shows 5 points of natural linearity.
Linearity
Samples containing and/or spiked with high concentrations of human CD21 were serially diluted with Sample Diluent to produce samples within the dynamic range of the assay

Stability & Storage
Background: CD21
CD21, also known as complement receptor 2 (CR2), is a 145 kDa transmembrane protein that contains 15 tandem SCR/SUSHI repeats. CD21 is primarily expressed on B cells, follicular dendritic cells, and T cells. It binds the complement component fragments iC3b, C3d, and C3d,g and forms complexes with CD19 and CD35. CD21 is required for germinal center development, antibody production, and B cell tolerance. It also functions as a cellular uptake receptor for Epstein-Barr virus.
