N-(t-butyl ester-PEG4)-N-bis(PEG4-Propargyl) is a trifunctional PEG linker that combines a t-butyl ester with two terminal alkynes. The alkynes can be applied in copper-click chemistry with azides to form stable triazole linkages with a target molecule, while the t-butyl ester can be deprotected and reacted with amines or alcohols to form amides or esters.

Product advantages
1. The instantaneous centrifugal function rises to the maximum speed for about 6 seconds, allowing for rapid detachment of hanging droplets from the wall;
2. Faster acceleration and deceleration rate, required to complete the experiment in a shorter time;
3. Door cover protection, overspeed and imbalance detection system, capable of real-time monitoring of the centrifugal process, ensuring the safe operation of the instrument; When the operation ends, an error occurs, or an imbalance occurs, the sound signal prompts, and the operation stops at the same time. The LCD displays the result code

Overview
Detection kits for the JCV
CE-IVD marked version available for in vitro diagnostic use
Available in TaqMan format for analysis
The JC virus (JCV) is a type of human polyomavirus and belongs to the family Papovaviridae. JCV is a double-stranded DNA virus, and is genetically similar to BK virus and SV40. The virus is very common in the general population and it is believed that most people acquire JCV in childhood or adolescence. Typically the infection is subclinical and no of consequence in children 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. However, it has not been established whether PML is the result of a primary infection with JCV in a person with impaired immunity or whether it follows reactivation of latent virus. JC virus is also the primary cause of nephropathy (kidney disease) in people who have received a kidney transplant and are on immunosuppressive therapy.

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.
