Overview

• Detection kits for the BKV/JCV
• Available in TaqMan format for analysis

The BK virus is a member of the polyomavirus family. It has been suggested that this virus may be transmitted through respiratory fluids or urine, since infected individuals periodically excrete virus in the urine. BK viral infections are typically asymptomatic in healthy individuals, however very mild symptoms may appear including mild respiratory infections and fever. Infections with BK virus in immunocompromised or immunosupressed patients are much more severe and may involve renal dysfunction. In fact, in kidney transplant patients the immunosupressive drugs required for the transplant may allow the virus to replicate within the graft, resulting in a disease called BK virus nephropathy (BKVN). The JC virus is a type of human polyomavirus and is very common in the general population, infecting 70 to 90% of humans. Most people acquire JCV in childhood or adolescence. Typically the infection is subclinical and no of consequence in individuals with healthy immune systems. The initial site of infection may be the tonsils or the gastrointestinal tract, and the virus then remains latent in the gastrointestinal tract. JCV can also infect the tubular epithelial cells in the kidneys, where it continues to reproduce, shedding virus particles in the urine. Also, JCV can cross the blood-brain barrier into the central nervous system. JCV is known to cause the usually fatal progressive multifocal leukoencephalopathy (PML) by destroying oligodendrocytes in the brain in immunodeficient or immunosuppressed individuals. The JC and BK viruses are very similar, with their genomes sharing 75% homology. It is however important to differentiate between the viruses due to the differences in pathology and especially the invariably fatal outcome of PML which is only caused by the JC virus.

The dsDNA Quantification Broad Range Kit and dsDNA Quantification High Sensitivity Kit are developed for double stranded DNA quantification using microplate readers. The DNA Quantification BR kit includes BR Dye, BR Dilution Buffer, and BR DNA Standards. The DNA Quantification HS kit includes HS Dye, HS Dilution Buffer, and HS DNA Standards. Simply dilute the Dye with the Dilution Buffer, add DNA sample, then read the concentration using microplate reader. The BR assay is accurate in the linear range from 4 to 1000 ng and the HS assay is accurate in the linear range from 0.2 to 100 ng. Both kits are highly selective for double-stranded DNA over RNA.

The Quantification Kits have several advantages over traditional DNA quantitation such as sensitivity, stability, and tolerance of contaminants.

Both kits reduce the cost of DNA quantification by 60% as compared to other brands.

Save 60% of the costs.

The performance of the kit is nearly identical to that of Thermo Fisher’s kit (figure below).

Common contaminants such as salts, free nucleotides, solvents, detergents, RNA, single stranded DNA, or protein are well tolerated in the assay (Table 1).

Description

Attogene’s 0.5mL Micro Spin Desalting Columns are convenient, simple, and ready to be used out of the box. We provide a product that facilitates equal, if not superior results to leading brands products at a significantly better cost. Superlative recovery of proteins and other macromolecules (>7000 MW) with greater than 95% retention of salts, and other small molecules (<1000 MW), are possible even with very dilute (25 ug/mL) samples. Our columns, which are constructed with a simple break away tab at the bottom, are comprised of polypropylene and contain our own proprietary resin slurry that we’ve developed in house to achieve optimal results. Sample volumes between 30-130uL can be loaded while still achieving expected purification numbers.
