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 rat folic acid 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 % 95

Range % 83-99  
1:4 Average % 96  
Range % 87-98  
1:8 Average % 94  
Range % 80-98  
The recovery of rat folic acid 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.

Regarding CSB-E08757r-1plate-we would like to know the origin of the standard Folic Acid? Is it derived from rat or baculovirus etc?

Thanks for your inquiry.
The standard is purified small molecule. Sorry we can not disclose the specific origin. Hope you could understand.

Sorry to bothering you, and I have questions about your product CSB-E08757r.
1) Could you let us know the chemical name and concentration of acid in Stop Solution?
2) Could you let us know whether any preservatives are contained in each component?”.

Thanks for your inquiry.
Stop solution is 4N sulfuric acid.
Preservative is proclin 300(1:3000).
