ViShield Saliva Collection Kit VTS004

ViShield Saliva Collection Kit is a DNA and RNA saliva collection kit designed for the collection and preservation of nucleic acids from saliva samples. This DNA and RNA saliva collection kit also takes a microbial snapshot of a sample while inactivating viruses making samples safe and ready for transport. Samples stored in the ViShield Saliva Collection kits are stable at ambient temperature, and can be frozen for longer-term storage. This DNA and RNA saliva collection kit simply requires users to deposit saliva into the spit cup, add the ViShield reagent, and shake vigorously to ensure proper stabilization.

PRODUCT FAQ

Q1: How to collect solid tissues in ViShield?

Transfer tissues in to ViShield at room temperature, submerge. Tissue can be homogenized or stored frozen prior to homogenization.

Q2: Can ViShield be used on extracted DNA and/or RNA?

Yes, extracted nucleic acids are stabilized in ViShield. Prior to downstream applications, clean-up the sample via the appropriate ViShield clean-up kit (Genomic DNA Clean and Concentrator (gDCC), DNA Clean and Concentrator (DCC), and RNA Clean and Concentrator (RCC)).

Q3: What sample types is ViShield suitable for?

 ViShield can be used on a wide variety of sample types including cells, tissues, biological fluids (plasma, serum, saliva, urine), and environmental samples (feces, plants, swabs, etc.).

Q4: How long can samples be stored samples in ViShield at ambient temperature?

RNA > 1 month 
DNA > 2 years

Q5: How long can samples be stored frozen in ViShield?

DNA & RNA (<-20°C): Indefinitely

Q6: A white precipitate occurred after thawing frozen samples stored in ViShield, is this normal?

Some components of the reagent (or sample) may have precipitated out of solution during the freeze-thaw process. Once the sample is thawed to ambient temperature, vortex the sample to bring precipitate back into solution. Furthermore, try heating samples in hand or 37°C for 5 minutes and vortex.

Q7: Do I need to homogenize the sample in  ViShield prior to storage?

No, tissues do not need to be homogenized.

Q8: Can I FACS sort directly into ViShield?

Yes, sort directly into ViShield (e.g. Collect 100 µl of FACS sorted cells into minimally 400 µl of ViShield).
