FIREScript® Reverse Transcriptase (RT) is a genetically engineered MMLV (Moloney Murine Leukemia Virus) based Reverse Transcriptase.

This is an RNA‐directed DNA polymerase that can synthesize a complementary DNA strand from ssRNA or ssDNA and is active over a broad range of reaction temperatures from 37°C to 60°C.

FIREScript® RT is a robust enzyme for RNA detection and has enhanced stability at room temperature with no activity loss for up to 1 month. This RT contains a functional RNase H domain which can increase the sensitivity of RT‐qPCR (quantitative reverse transcription PCR).

Does RiboGrip help with inhibitor resistance?

RiboGrip™ is not directly associated with tolerance to common inhibitors, however, it helps to keep RNA intact and prevent RNA degradation because RiboGrip is inactivating ribonuclease enzymes

Enzymes are usually very viscous liquids. What would you recommend for the most accurate pipetting?

Pipetting viscous liquids like glycerol with an air displacement micropipette is difficult, because viscous liquids have a high resistance to flow. We have a few recommendations for accurate pipetting:

  • Hold the pipette vertical, since more liquid gets picked up into the tip when the pipette is held at an angle.
  • Only put the pipette tip in the liquid.
  • Use a very slow aspiration speed, wait for a few seconds until the liquid retightens and then use a very slow dispensing speed.
What are the storage conditions and stability of Solis BioDyne reagents?

Solis BioDyne products should be stored at -20°C.

Shipping and temporary storage for up to 1 month at room temperature (*1525°C) has no detrimental effects on the quality of Solis BioDyne reagents.

Freeze-thaw stability is tested for each product. Most PCR and qPCR products have passed 30 freeze-thaw cycles with no changes in performance. Specific information is found in Storage and Shipping conditions of each product.

When stored and handled under the recommended conditions, full activity of the reagents is retained until the Expiry Date printed on the tube label.
