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 CLEC9A in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. Sample Serum(n=4) 1:1 Average % 89 Range % 85-93 1:2 Average % 104 Range % 100-108 1:4 Average % 89 Range % 85-93 1:8 Average % 108 Range % 104-112 -
回收率：
The recovery of human CLEC9A spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section. Sample Type Average % Recovery Range Serum (n=5) 88 84-93 EDTA plasma (n=4) 106 103-109 -

功能：Functions as an endocytic receptor on a small subset of myeloid cells specialized for the uptake and processing of material from dead cells. Recognizes filamentous form of actin in association with particular actin-binding domains of cytoskeletal proteins, including spectrin, exposed when cell membranes are damaged, and mediate the cross-presentation of dead-cell associated antigens in a Syk-dependent manner.
