The Aurum total RNA 96 kit isolates high-quality DNA-free total RNA from cultured cells, bacteria, and yeast in a 96-well format for high-throughput total RNA isolation. The kit utilizes a stringent reagent composed of guanidine isothiocyanate and β-mercaptoethanol for efficient sample lysis and quick RNase inactivation, followed by purification on silica membrane in a 96-well plate format using a spin- or vacuum-mediated protocol. The entire purification process, including DNase I digest, is completed in less than 60 minutes. Isolated RNA is of the highest integrity and is suitable for the most discriminating applications.
