Lysis Tube W/Swab Microbe VTR1104

ViShield Lysis and Collection tubes are microbial lysis tubes and bead beating tubes designed for the streamlined collection, transport, and processing of biological specimen. The microbial lysis tubes and bead beating tubes are pre-filled with  ViShield and a lysis matrix tailored for tough-to-lyse- sample inputs from tissue to microbial samples. Collected samples do not require additional handling for processing and are ready for homogenization. Bead sizes include 0.5mm & 0.1mm (R1103 and R1104) and 2.0mm (R1105).

Product Features


Q1: 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.).

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 Zymo Research clean-up kit (Genomic DNA Clean and Concentrator (gDCC), DNA Clean and Concentrator (DCC), and RNA Clean and Concentrator (RCC)).

Q3: How long can samples be stored samples in ViShield at ambient temperature?

RNA > 1 month 
DNA > 2 years

Q4: How long can samples be stored frozen in ViShield?

DNA & RNA (<-20°C): Indefinitely

Q5: 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).

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: 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.
