DBCO-PEG1-NHS ester

Methyltetrazine-PEG5-DBCO is a TCO reactive reagent with a DBCO group and water-soluble PEG spacer. This reagent can be used to convert azido-containing peptides or proteins into tetrazine-modified peptides or protein without catalyst or axillary reagents. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description

• Description

Aflatoxin is the most common food toxin that is harmful to human and animal health. The most frequent aflatoxins are B1, B2, G1, and G2, which can affect the body through respiratory, mucosal, or cutaneous routes, causing an excessive inflammatory response. Aflatoxin can infect crops during their growing stages or even after they are harvested. It mainly targets the liver and can impair the effectiveness of immunization in children, increasing the risk of infection. Aflatoxin detection and quantification in food and feed is a critical part of food and feed safety concerns.

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.
