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

Please provide the following information regarding Human Cross-linked Carboxy-terminal telopeptide of type I collagen, CTX-I ELISA Kit CSB-E11224h
a. Is the capture antibody a monoclonal or polyclonal?
b. What is the host of the capture antibody?
c. Is the detection antibody a monoclonal or polyclonal?
d. What is the host of the detection antibody?
e. B208. What’s is that standard? A recombinant protein or something else? If a recombinant protein, what is the host?
f. If recombinant protein, is it full length or partial?
g. What is the species of the standard– human or something else?

Thanks for your inquiry.
