t-Boc-N-Amido-PEG8-propargyl has an alkyne group and Boc-protected amine. The alkyne group reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The deprotection of Boc-protected amine can be peformed under mild acidic conditions. The hydrophilic PEG chain enhances the solubility of the molecule in aqueous solution. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

Storage Conditions and Product Stability
All kit components can be stored for 2 years 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.

Description
FluoroVue™ Nucleic Acid Gel Stain (10,000X) is specially designed for in-gel use and is a safer replacement for conventional Ethidium bromide (EtBr), which poses a significant health and safety hazard to its users. It is a fluorescent stain which offers highly sensitive detection of double-stranded or single-stranded DNA and RNA in a convenient manner. FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity that is several times greater than EtBr.
FluoroVue™ Nucleic Acid Gel Stain is compatible with both conventional UV gel-illumination systems as well as harmless long wavelength blue light illumination systems, like B-BOX™. When bound to nucleic acids, FluoroVue™ Nucleic Acid Gel Stain has a fluorescent excitation maximum of 250 and 482 nm, and an emission maximum of 509 nm. Therefore, it can replace EtBr without the need of changing existing lab imaging systems.
