精密度：
Intra-assay Precision (Precision within an assay): CV%<8% Three samples of known concentration were tested twenty times on one plate to assess. Inter-assay Precision (Precision between assays): CV%<10% Three samples of known concentration were tested in twenty assays to assess. -
線性度：
To assess the linearity of the assay, samples were spiked with high concentrations of human C1S in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

功能：C1s B chain is a serine protease that combines with C1q and C1r to form C1, the first component of the classical pathway of the complement system. C1r activates C1s so that it can, in turn, activate C2 and C4.
