Q:

Please confirm whether this kit can be used with Saliva samples and also suggest suitable protocol for saliva sample preparation.

A:
Thanks for your inquiry. CSB-E09771h ,we used it to test human saliva before and the value was ND--62.5pg/ml.
Here is the processing method on saliva sample preparation.You can take it as reference:Remove particulates by centrifugation for 10 minutes at 4000x g at 2-8°C and assay immediately or aliquot and store samples at -20°C. Avoid repeated freeze-thaw cycles. Recommend to use fresh saliva samples.

    9. Vaspin may play an important compensatory role in obesity and insulin resistance in elderly people. PMID: 28553648
    10. Studied the effects of vaspin on lipopolysaccharide (LPS)induced acute respiratory distress syndrome (ARDS) in vivo and in vitro, and further explored the molecular basis and potential mechanisms underlying these effects.
