Diagnoses using exosomes derived from saliva have been attracting great attention in recent years due to the

ease of sample collection. However, saliva samples are challenging when it comes down to exosome

isolation. In addition to cells and cell debris, large amount of amylase, mucin and glycoprotein present in

saliva, making the samples viscous and hard to manipulate. Pre-treatments, such as sonication and dilution,

are often required. In many cases, the salivasamples can still be difficult to handle even after pre-treatments.

This product is specifically designed to address these issues using the proprietary saliva filters. Highly

viscous saliva samples can be converted to non-viscous solution instantly by passing the samples through

the filter. Exosomes can then be readily precipitated from as less as 100 µl saliva using the highly effective

non-PEG-based reagent.
