Plasmid Purification Magnetic Beads (RNA Depletion)

Plasmid isolation from bacterial cultures is one of the most popular techniques in biomedical research and pharmaceutical industries. However, it is common that the isolated plasmid DNA is usually contaminated with varied degrees of host RNA. Plasmid purification is necessary to reduce the impact on downstream applications by removing RNA contamination.

We have developed a simple reagent to completely remove RNA contamination in the isolated plasmid samples using Solid Phase Reversible Immobilization (SPRI) beads. SPRI beads consist of paramagnetic particles coated with carboxyl groups that reversibly bind DNA. Our Plasmid Purification Magnetic Beads (RNA Depletion) combines BioDynami’s proprietary chemistries with the reversible DNA-binding properties of SPRI magnetic beads. The reagent removes RNA and recovers the plasmid in the same step.  Moreover, unwanted components such as salts, dNTPs, proteins, enzymes, and other impurities can also be removed simultaneously.

Plasmid can be used for downstream applications such as enzymatic digestion, transformation, transfection and molecular cloning etc.  The beads can be an effective and inexpensive reagent for bacterial RNA depletion for routine plasmid purification.

Features

• Effective depletion of bacterial RNA by RNase
• High recovery rate of plasmid DNA by magnetic beads
• Removal of unwanted components and impurities
• Simple and fast beads-based protocol

Introduction

MagZol Reagent is a reagent system for the isolation of total RNA from cells and tissues. The reagent, a single-phase solution consisting of phenol and guanidine isothiocyanate, is modification of the single-step RNA isolation method developed by Chomczynski and Sacchi. The sample is homogenized and lysed in MagZol Reagent which maintains the integrity of the RNA, while disrupting and denaturing endogenous RNases and other cellular components. Extraction of the lysate with chloroform further denatures proteins and separates the mixture into an organic and an aqueous phase. RNA remains exclusively in the aqueous phase, and is subsequently recovered by isopropanol.

This method is suitable for small quantities of tissue (<100mg) and cells (<5 X10⁶), and large quantities of tissue (up to 1g) and cells (<10⁸), of human, animal, plant, or bacterial origin. The simplicity of the MagZol Reagent method allows simultaneous processing of a large number of samples. The entire procedure can be completed in one hour. Total RNA prepared in this manner can be used for Northern blot analysis, dot blot hybridization, poly(A) + selection, in vitro translation, RNase protection assay, and molecular cloning. For use in amplification by thermal cycling, treatment of the isolated RNA with RNase-free DNase I is recommended when the two amplimers lie within a single exon.

Advantages

• Extensive – suitable for various kinds of biological samples, including animals, plants, cultured cells, bacteria, etc.
• High yield – efficient cleavage releases more RNA
• High purity – purified RNA is suitable for various downstream applications
• Flexible – sample amount can be adjusted according to the demand
• High cost performance compared with similar products

Storage and Stability

MagZol Reagent should be stored at 2-8°C upon arrival and is stable for at least 24 months under the condition. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance.
