Q&A and Customer Reviews


Please could you tell us if you have a Mouse Leptin ELISA Kit that can
be used on only 5 ul of serum?

Thanks for your inquiry.
5ul sample is really too little and at least 1:20 dilution is needed if you dilute the sample.
However, for this kit CSB-E04650m, usually there is no need to dilute serum and plasma sample.
So we hope you could try to collect more samples and make the experiment according our manual.

Target Data
