Description
Glycerol-free, lyo-ready formulation of Ultima H RNase Inhibitor, designed for mixes and assays to be lyophilized. Ultima H is a highly engineered RNase inhibitor of human origin with the highest thermal stability and almost absolute oxidation resistance: it inhibits the activity of common RNases found in human tissues and body fluids and does not interfere with reverse transcriptases, DNA and RNA polymerases.
Key features
Formulated without glycerol for lyophilized RT-PCR and RT-qPCR mixes and assays.
The only protein RNase inhibitor active at temperatures above 55 °C, enabling reverse transcription at higher temperatures with increased yield and sensitivity.
The only truly oxidatively resistant RNase inhibitor: retains full activity without DTT and even at 2.0 % H2O2.
Protects 100 % of RNA during direct RT-qPCR from human serum and saliva.
Remains fully active in alkaline pH (9.0) and broader assay conditions than competitors.
Applications
- Lyophilized RT-PCR and RT-qPCR mixes and assays
- One-step RT-qPCR
- Two-step RT-qPCR
- Direct RT-PCR from human samples
- In vitro transcription and translation
- RNA-seq library preparation
