Intra-assay Precision (Precision within an assay): CV%<10%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<15%
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 PLAP in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

I would like to know whether the CSB-E09160h - Cusabio ELISA kit (quotation as attached) is able to quantify recombinant proteins (non-native)?
A:
Thanks for your inquiry. As in recombinant protein ,there is difference on expression system ,expression region and posttranslational modification,ect,we are not sure if recombinant proteins can be detected out.If the conformation of your recombinant proteins is same with native proteins ,then our kit can quantify it.
