DB Ultima H RNase Inhibitor Lyo-Ready: Ultimate protection

DB Ultima H RNase Inhibitor: Absolute RNA Protection with Lyo-Ready Variant

(DB-1307)

Scientists often blame the RNA for bad results. But in most cases the RNA is just a victim. Your RNA didn't fail. Your RNase inhibitor did!

Protect your RNA against degradation with our DB Ultima H RNase Inhibitor, the ultimate solution for RNase inhibition, offering exceptional resistance to oxidation.

Highly engineered RNase inhibitor of human origin with full oxidative resistance and unparalleled thermal stability. It outperforms all other RNase inhibitors on the market!

DB Ultima H RNase Inhibitor is now available in a Lyo-Ready formulation for seamless integration into lyophilized RT-PCR and diagnostic reagent mixes.

See the complete info in our DB Ultima H RNase Inhibitor leaflet!

Package size

Key Parameters: How does DB Ultima H improve your RNA protection?

Thermal Stability: The only protein inhibitor stable at or above 55°C.

High Potency: Highest possible inhibition of human RNases. Inhibits also other eukaryotic and E.coli RNases.

Extraordinary Resilience: Stable for months at room temperature. Fully active without DTT, cannot be oxidized. Compatible with the widest range of buffers & pH. Survives multiple freeze/thaw cycles.

Direct RT-PCR ready: Even higher activity than human RNase inhibitor in human tissues. Higher temperature ensure increased yields and sensitivity.

Lyo-Ready: Glycerol-free and detergent-free RNase inhibitor formulation designed for incorporation into lyophilized molecular biology and diagnostic reagent mixes.

Stop relying on unstable DTT to protect your RNA. DB Ultima H is the only inhibitor fully active without it.

DB Ultima H is the only oxidatively resistant inhibitor:Standard inhibitors on the market are very limited in oxidative resistance. This leaves the DB Ultima H the only truly oxidative resistant inhibitor even with 2% hydrogen peroxide use with no DTT. Numbers represent the same order of RNase inhibitors as it is in the first graph.

DB Ultima H stays fully active through freeze/thaw cycles that completely destroy standard inhibitors.

Freeze/thaw cycle stability:Left: Residual RNase inhibitor activity in RT-PCR buffer with fresh 1mM DTT after a single freeze/thaw cycle at -20℃. Right: Residual RNase inhibitor activity in RT-PCR buffer with fresh 1 mM DTT after 24 hours on wet ice.

Maximize your RT-PCR sensitivity and yields: DB Ultima H stays fully active at 55°C, a temperature that completely destroys standard inhibitors.

Residual RNase Inhibitor activity after 5 min incubation at 55 ℃ in optimal buffer :DB Ultima H will enable RT-PCR in direct RT-qPCR at higher temperature; increasing yields and sensitivity 55°C is the optimal temperature for mutated M-MLV reverse transcriptase and optimal for UDG system.

Applications: DB Ultima H ensures RNA protection with no enzyme interference

Single-Cell Profiling & In Vitro Assays: Full RNA integrity guaranteed for prolonged in vitro protocols and single-cell expression profiling with zero enzyme interference.

RNA Structural & Functional Studies: Work across broad pH ranges and without DTT to establish perfect native conditions, completely free from the risk of sample degradation.

Direct RT-PCR from Human Samples: Bypass purification and amplify directly from crude lysates. Exceptional potency and oxidative resistance neutralize aggressive, RNase-rich environments in complex human tissues.

cDNA Synthesis & Cloning: Guarantee full-length transcripts. Safely melt complex secondary RNA structures at 55°C to maximize cDNA synthesis yields, without compromising downstream enzymatic steps.
