Precision

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.

Linearity

To assess the linearity of the assay, samples were spiked with high concentrations of human CPN2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

Function
(From Uniprot)
The 83 kDa subunit binds and stabilizes the catalytic subunit at 37 degrees Celsius and keeps it in circulation. Under some circumstances it may be an allosteric modifier of the catalytic subunit.
Gene References into Functions
  1. Real-time PCR and western blotting show the following CPN2 expression: minimal in MDA-MB-468 cells but obvious in MDA-MB-231 and MCF7 cells. MDA-MB-231 breast cancer cell lines were selected for the control group and CPN2 was knocked out for the experimental group. PMID: 26860443
Subcellular Location
Secreted.
