Product Description

Murine RNase Inhibitor is purified from a recombinant strain of E. coli in a soluble form. It specifically inhibits the activity of RNases A, B and C through binding noncovalently in a 1:1 ratio with high affinity. Recombinant murine RNase inhibitor does not contain 2 oxidation-sensitive cysteines which are contained in human-origin RNase inhibitor. Therefore, murine RNase inhibitor has high anti-oxidation activity and is more stable for low DTT experiments (< 1mmol/L). This product is validated for its compatibility with HifairTM Ⅱ Reverse Transcriptase (Cat#11110) and various DNA Polymerases. Murine RNase inhibitor is ideal for high-DTT-sensitive experiments, such as RT-PCR. The product can be used in cDNA Synthesis, polysome isolation, and In vitro transcription/translation.

Shipping and Storage

The product is shipped with ice packs and can be stored at -20°C for 2 years.

Unit Definition

The required amount of RNase Inhibitor to inhibit 50% activity of 5-ng RNase A is defined as one unit. The activity of RNase A is measured by hydrolyzing cyclic 2', 3'-CMP to generate 3'-CMP.

Cautions

1. The product works in a wide pH range and exhibits maximal inhibitory activity at pH 7~8.

2. Please handle the product gently to avoid inactivation.

3. This product does not inhibit RNase H.

4. For your safety and health, please wear lab coats and disposable gloves for operation.
