T7 RNA Polymerase
Lyophilized.

The same highly processive, strictly T7-promoter-specific enzyme (5′ TAATACGACTCACTATAG 3′), purified with our ArtPure™ process to >99% purity, animal origin-free and free of proteinases, RNases and DNases — now lyophilized in a stable form. For eco-friendly, reliable, cost-effective and convenient handling, our lyophilized T7 is the superior choice: it ships without cold chain, reducing shipping complexity, cost and environmental footprint.

Definitions

Activity (U/µl): One enzyme unit incorporates 1 nmol of soluble RNA nucleotides into insoluble polymeric RNA per hour at 37°C.
Purity: Evaluated by SDS-PAGE, where the integrated peak area of the RNA Polymerase is compared to other protein peaks in the same lane.
RNA yield: Quantification of total RNA products after in vitro transcription and RNA purification, compared to leading suppliers.
dsRNA by-products: Quantification of double-stranded RNA by-products using a dsRNA-specific ELISA, compared to leading suppliers.

Reconstitution & storage.

Optimal reconstitution and storage conditions ensure prolonged enzyme function.

Enzyme reconstitution

Reconstitute with the provided buffer upon receipt. Add 100 µl of the supplied storage buffer to the bottom of the tube, avoiding contact between the pipette tip and the pellet. Incubate 5 minutes on ice, or until the buffer has been completely absorbed. Mix by carefully pipetting several times — do not vortex. Note that modifying the resuspension volume may affect RNA yields.

Storage upon receipt

Stable at −20°C for up to 12 months once reconstituted in the glycerol-based supplied buffer. For extended storage, we recommend aliquoting in smaller volumes, freezing at −80°C and avoiding repeated freeze-thaw cycles.

Storage buffer

50 mM Tris-HCl, 100 mM NaCl, 20 mM DTT, 1 mM EDTA, 50% glycerol, 0.1% Triton X-100, pH 7.9. Shipped at ambient temperature — we recommend storing at −20°C upon receipt.
