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

t-Boc-N-amido-PEG4-Amide-Tri-(propargyl-PEG10-ethoxymethyl)-methane is a branched crosslinker molecule with three terminal propargyl groups and a t-Boc protected amide group. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected under acidic conditions. Reagent grade, for research use only.

RNA into DNA and PCR in one step? Then, this enzyme will simplify PCR analysis from RNA templates reducing labor and time. RT-KTQ2 was evolved from the thermostable KlenTaq DNA polymerase with no significant reverse transcriptase activity. Four mutations ensure that the variant is reverse transcriptase active and even PCR active, while maintaining the thermostability. This allows to perform reactions at high temperatures minimizing problems encountered with strong secondary structures in RNA that melt at elevated temperatures. For further information refer to the original publication.
