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.

Overview

• Detection kits for WNV
• CE-IVD marked version available for in vitro diagnostic use
• Available in TaqMan format for analysis

West Nile Virus (WNV) belongs to the RNA virus family of Flaviviridae. It is known to spread primarily through arthropod vectors such as mosquitoes. The virus infects mainly birds but is also reported to infect humans as well as pets such as cats and dogs. In humans, the majority of the infections caused by WNV are asymptomatic. However, some individuals (the majority of the confirmed cases) could enter a second, febrile stage with flu-like symptoms – commonly known as West Nile Fever. In a more serious stage, the disease becomes neuroinvasive, causing meningitis or encephalitis. Such severe conditions could lead to mortality. As the symptoms of WNV are very similar to other common diseases but can be fatal at a severe stage, it is important to distinguish the virus early in the diagnosis, particularly at the molecular level.

Storage Conditions and Product Stability
All kit components can be stored for 1 year after the date of production without showing any reduction in performance.

All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
