Bacteria RNA Mini Kit (RBB050, RBB100, RBB300) without DNase

RNA Extraction/Total RNA

The Presto™ Mini RNA Bacteria Kit was designed for total RNA purification from Gram (-) negative bacteria and Gram (+) positive bacteria using an efficient RNA miniprep system. This RNA Kit includes Bacteria Lysis Buffer and Lysozyme to reduce sample preparation time and minimize hands on time. The Presto™ Mini RNA Bacteria Kit uses detergents and chaotropic salt to lyse cells and inactivate RNase. RNA in the chaotropic salt is bound by the glass fiber matrix of the RNA spin column and once any contaminants have been removed, using the Wash Buffer, the purified total RNA is eluted by RNase-free Water. High quality total RNA can be purified within 20 minutes and is ready for use in RT-PCR, Northern Blotting, Primer Extension, mRNA Selection and cDNA Synthesis. Each Geneaid RNA Kit includes individually packaged certified DNase and RNase-free spin columns and collection tubes.

QUALITY CONTROL

The quality of the Presto™ Mini RNA Bacteria Kit is tested on a lot-to-lot basis according to Geneaid's ISO-certified quality management system. The purified RNA from Escherichia coli cells (up to 1 x 109), (A260/A280 ratio of 1.8-2.0) is quantified with a spectrophotometer and checked by electrophoresis.

Presto™ Mini RNA Bacteria Kit Functional Test Data

*

Figure 1 .RNA was extracted using the Presto™ Mini RNA Bacteria Kit. An Escherichia coli (1×109) culture (OD600=1.3, 1 ml) was harvested by centrifugation at 16,000 x g for 1 minute. 10 µl from a 50 µl eluate of purified RNA was analyzed by electrophoresis on a 0.8% agarose gel.

Figure 2 .Escherichia coli RNA was purified using Presto™ Mini RNA Bacteria Kit. The integrity and quality of RNA were determined by Qubit with RNA integrity and quality (IQ) assay kit. The IQ 9.1 score showed 91% large and structured RNA (including mRNA, tRNA and rRNA) was in the purified RNA.
