Assay Principle
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.    
To assess the linearity of the assay, samples were spiked with high concentrations of human PIVKA-II 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 % 94  
Range % 90-101  
1:2 Average % 97  
Range % 86-101  
1:4 Average % 96  
Range % 90-108  
1:8 Average % 94  
Range % 82-103  
The recovery of human PIVKA-II 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.

I have a question regarding calibration standard in the kit. How this standard protein synthesized or extracted from some source? and how many des-carboxy forms (PIVKAII) it includes?

Thanks for your inquiry.
PIVKA-II, also known as de-gamma-carboxyl prothrombin (DCP), is an abnormal form of prothrombin.
The standard is a special protein. Sorry that the specific preparation method is confidential and we can not disclose it. The standard is provided in the form of lyophilized powder, and the corresponding protective components will be added in it. The concentration is 20 ng/ml after re-suspension.Pls let me know if you have any further questions. Thank you.

Can you please let me know the below information:
1) Does the kit contain any human derived material? If so, please describe what it is.
2) Does the kit contain any animal derived material? If so please describe what it is. Please let us know if it contains polyclonal or monoclonal antibodies and what species the antibodies are from?

Thanks for your inquiry. CSB-E13343h
Some components in the kit contain BSA.
There are 2 antibodies in the kit. Capture antibody is mouse monoclonal antibody and detection antibody is rabbit polyclonal antibody.Pls let me know if you have any further questions. Thank you.
