Dilution of sample
It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.17-120 nmol/mL).
The recommended dilution factor for different samples is as follows (for reference only):
