Solid Phase Reversible Immobilization (SPRI) beads are a simple and effective reagent for DNA purification, but not for short oligo purification. The beads are paramagnetic particles coated with carboxyl groups that can reversibly bind to nucleic acid. However, SPRI beads can only purify DNA/RNA fragments that are 100 base pairs or longer. DNA/RNA fragments shorter than 100 base pairs are not effectively recovered.
Detail
Magnetic Beads (Short Oligo Purification)
Solid Phase Reversible Immobilization (SPRI) beads are a simple and effective reagent for DNA purification, but not for short oligo purification. The beads are paramagnetic particles coated with carboxyl groups that can reversibly bind to nucleic acid. However, SPRI beads can only purify DNA/RNA fragments that are 100 base pairs or longer. DNA/RNA fragments shorter than 100 base pairs are not effectively recovered.
Oligo purification can also be performed using spin column-based technology. The oligo size limitation for recovery is around 20 nt, as oligos under 20 nt have a very low recovery rate.
We have developed Magnetic Beads (Short Oligo Purification) Kit for short oligo purification. Our proprietary bead technology enables the recovery of oligos as short as 6 nt. 80% of the 6 nt oligos and 90% of the > 8 nt oligos can be recovered. The reagent also effectively removes impurities and unwanted components such as salts, proteins, dNTPs, detergents, and other contaminants. The magnetic bead reagents are RNase free, and can be used for both DNA and RNA applications.
Recovery rates of of short oligos. Oligos with different sizes were used as input. BioDynami Short Oligo Quantification Kit (Cat. # 40046) was used to quantify the recovery rates with modifications.

Removal of impurities and unwanted reaction components
Mucin 6 (MUC6) is a glycoprotein expressed in mucous neck cells, pyloric glands of the antrum, epigastric and bronchial epithelium, and in Müller ducts of the endocervix and urethral epithelium. Anti-MUC6 is useful for differentiating fetal, precancerous, and cancerous colonic mucosa from normal colon, as the antibody does not stain the latter. Anti-MUC6 stains the gastric epithelial surface of normal human gastrointestinal tract.
Robust lysis buffer is well-suited to even challenging samples such as pine needle, grape leaf, etc
Isolate total RNA (including microRNA) without phenol
Isolated RNA is of high quality, integrity and diversity
Also available in 96-well format for high throughput applications
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
Norgen’s Plant/Fungi Total RNA Purification Kit provides a rapid method for the isolation and purification of total RNA, including virus and viroid RNA, from a wide range of plants. Total RNA can be purified from fresh or frozen plant tissues, plant cells or filamentous fungi samples using this kit. All sizes of RNA are purified, including microRNA (miRNA) . The procedure is rapid and convenient.
The RNA is purified without the use of phenol or chloroform. The purified RNA is of the highest quality, and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
Norgen’s Plant/Fungi Total RNA Purification Kit is also available in a 96-well (High Throughput) format for high throughput applications. Purification with the 96-well plates can be performed using either a vacuum manifold or centrifugation.
