Magnetic Beads (tRNA Purification)

Solid Phase Reversible Immobilization magnetic beads has been used for nucleic acids purification because they are effective, simple, and fast. The carboxyl groups coated beads are paramagnetic particles that reversibly bind to nucleic acid. However, there is a drawback for magnetic beads that it can only purify DNA/RNA that are 100 base pairs or longer. tRNA and other DNA/RNA fragments shorter than 100 base pairs are not effectively recovered. We have developed Magnetic Beads (tRNA Purification) to overcome the hurdle.

The Magnetic Beads (tRNA Purification) solves the tRNA and short DNA/RNA purification problem. The beads with our proprietary technology purify tRNA effectively by removing impurities and unwanted components such as dNTPs, detergents, salts, proteins, and other contaminants. The magnetic bead reagents can be used for oligo (>70 nt) applications.

Workflow without large RNA/DNA contamination

In the case of samples contaminated with RNA/DNA such as rRNA and DNA, our magnetic beads can effectively remove RNA/DNA that are 180 nt and larger. Purified tRNA are ideal for applications requiring high quality, as the fragments are free of impurities and contaminants.

Workflow with large RNA/DNA contamination

Comparison of tRNA and 70 nt oligos recovery. BioDynami beads (tRNA purification) successfully recovered DNA fragments both yeast tRNA and 70 nt oligos.

Recovery of tRNA and 70 nt oligos with BioDynami magnetic Beads (tRNA Purification). Yeast tRNA and 70 nt oligos were used as input. Input and recovered oligos were quantified with ssDNA Quantification kit (BioDynami Cat. # 40043) and RNA Quantification kit (BioDynami Cat. # 40044).

Overview

• Isolate high quality, high yield plasmid DNA
• Plasmid DNA is ready for various downstream applications including restriction digestion, bacterial transformation, sequencing and more
• Available in 4 formats: MiniPrep, MiniPrep (Magnetic Bead System), 96-Well MiniPrep (Magnetic Bead System), and MaxiPrep

These kits are designed for the rapid preparation of plasmid DNA from Escherichia coli.

Plasmid MiniPrep Kit

This kit is designed for the rapid preparation of plasmid DNA from small cultures of Escherichia coli using convenient spin columns. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. This kit is able to purify plasmids up to 13,000 bp in size, and the typical purification yield is up to 20 μg from 1.5 mL of bacterial culture. Purified DNA is of excellent quality for transformation, restriction enzyme digestion, sequencing and more. Also available in a 96-well format.

Plasmid MiniPrep Kit (Magnetic Bead System and High Throughput Magnetic Bead System)

Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is designed for the rapid preparation of plasmid DNA from small batch cultures of Escherichia coli. Norgen’s magnetic beads bind DNA under optimized salt concentrations and release the bound DNA under low salt and slightly alkali conditions. The plasmid DNA is preferentially purified from other cellular components such as genomic DNA and RNA. The purified plasmids are fully digestible with all restriction enzymes tested, and are completely compatible with real-time PCR and NGS.

Norgen’s Plasmid MiniPrep Kit (Magnetic Bead System) is also available in a 96-well (HT) format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.

Plasmid MaxiPrep Kit

This kit is designed for the rapid spin column preparation of plasmid DNA from up to 100 mL of Escherichia coli cultures. The kit allows for the isolation of plasmid DNA with final endotoxin levels of 0.1 EU/µg of DNA or less. The kit is able to purify plasmids up to 13,000 bp in size, and typical yields from a 100 mL culture for a high copy number plasmid are between 0.4 and 1.0 mg. The purified DNA is fully digestible with all restriction enzymes tested, and is completely compatible with manual or automated sequencing to achieve 95-100% accuracy.

N-(t-butyl ester-PEG4)-N-bis(PEG4-Propargyl) is a trifunctional PEG linker that combines a t-butyl ester with two terminal alkynes. The alkynes can be applied in copper-click chemistry with azides to form stable triazole linkages with a target molecule, while the t-butyl ester can be deprotected and reacted with amines or alcohols to form amides or esters.
