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

Overview

• Fast, reproducible and easy processing of samples
• High yield and high quality genomic DNA with no RNA or protein contamination
• DNA ready for any application including PCR, qPCR, genotyping and more

Norgen’s Cells and Tissue DNA Isolation Kits are designed for the rapid preparation of genomic DNA from cultured cells as well as various tissue samples and urine. The purified genomic DNA is fully digestible with all restriction enzymes tested, and is completely compatible with PCR and Southern Blot analysis.

Cells and Tissue DNA Isolation Kit (Spin Column)

Purification is based on spin column chromatography as the separation matrix. Norgen’s columns bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The protocol can be completed in approximately 30 minutes for cells and within 90 minutes for tissues. Each kit contains sufficient materials for 50 preparations.

Cells and Tissue DNA Isolation Micro Kit (Micro)

Optimized for small inputs of cells and tissues, such as Laser-Captured Microdissection (LCM). Purification is based on spin column chromatography as the separation matrix. Norgen’s columns bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. Preparation time for a single sample is approximately 60 minutes, and each kit contains sufficient materials for 50 preparations.

Cells and Tissue DNA Isolation Kit (Magnetic Bead System)

Purification is based on the use of magnetic beads that bind DNA under optimized binding conditions. Norgen’s Cells and Tissue DNA Isolation Kit (Magnetic Bead System) allows for the isolation of genomic DNA from various types of animal tissues or cell samples. Preparation for 10 purifications is approximately 40 minutes of hands-on time.

Cells and Tissue DNA Isolation 96-Well Kit (High Throughput Magnetic Bead System)

Purification is based on the use of magnetic beads that bind DNA under optimized binding conditions. Norgen’s Cells and Tissue DNA Isolation 96-Well Kit (Magnetic Bead System) allows for the isolation of genomic DNA from various types of animal tissues or cell samples. The Cells and Tissue DNA Isolation 96-Well Kit (Magnetic Bead System) also can be integrated with a robotic automation system.
