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 CTX-Ⅱ in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

I want an citation/publication about Human Cross Linked C-Telopeptide Of Type II Collagen ,CTX-2 ELISA Kit CSB-E14328h in urine samples. Do you have any papers?

Thanks for your inquiry.
This kit can be used to test urine samples.
We tested human normal urine samples before and the test value is 0.3--1.25ng/ml. Some customers said the detection rate is very low. I will send you the manual and published reference by e-mail to you soon.Pls let me know if you have any further questions. Thank you.
