Company:

Thermo Scientific

Product Name:

RNase A, DNase and Protease Free

Catalog Number:

EN0531

I used Thermo Scientific RNase A to degrade unprotected mRNA during a gel retention assay to evaluate the protective effect of lipid nanoparticles (LNPs). Using 1 µL RNase A provided efficient RNA digestion while allowing clear discrimination between protected and degraded mRNA.

Experimental Design and Results Summary

Application

RNase digestion during gel retention assays to evaluate mRNA protection and encapsulation by lipid nanoparticles (LNPs).

Starting Material

Tips

Use 1 µL RNase A per sample under RNase-free conditions. Include untreated controls to compare RNA degradation and verify LNP-mediated protection. Handle all reagents using RNase-free consumables to avoid contamination.

Results Summary

Treatment with 1 µL RNase A efficiently degraded unprotected mRNA, while mRNA encapsulated within lipid nanoparticles remained protected until particle disruption. The enzyme produced consistent and reproducible digestion, allowing clear interpretation of gel retention assay results.

Summary

The Good

Rapid and efficient RNA degradation.

The Bad

Careful RNase-free handling is essential to prevent accidental degradation of experimental RNA samples.

The Bottom Line

Thermo Scientific RNase A is an excellent reagent for gel retention assays and other RNA integrity studies. Using 1 µL consistently produced complete degradation of exposed mRNA while allowing clear assessment of the protective capacity of lipid nanoparticles, making it a reliable tool for formulation characterization.
