The Raffinose/D-Galactose test kit allows for the specific and rapid measurement of raffinose and D-galactose in plant materials and food products.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).
Norgen’s Nuclease-Free Water is free of all DNases, RNases and nucleic acids and is suitable for all molecular biology applications requiring nuclease-free water including PCR, RT-PCR and real-time PCR. Our water is prepared without the use of DEPC, and is ready to use without further treatment.
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.
