DBCO-PEG5-NHS Ester is a DBCO-containing PEG linker containing NHS ester that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. PEG5 spacer increases the water solubility of compounds in aqueous media. DBCO is commonly used for copper-free Click Chemistry reaction. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Propargyl-PEG4)-N-bis(PEG4-acid) is a branched crosslinking reagent with a propargyl group and two terminal carboxylic acids. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The terminal carboxylic acids can react with primary amino groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Spring Viremia of Carp is caused by Rhabdovirus carpio, a bullet-shaped RNA virus. The disease has been reported in common carp (or koi) (Cyprinus carpio), grass carp (Ctenopharyngodon idella), bighead carp (Aristichthys nobilis), silver carp (Hypophthalmichthys molitrix), and Crucian carp (Carassius carassius), a close relative of the goldfish. Recent evidence suggests that common goldfish (C. auratus) are also susceptible. The disease was initially diagnosed in Yugoslavia (Fijan et al. 1971). Since then, it has been identified in other European countries, Russia, and the Middle East. Mortality has reached 70% in yearling carp from European populations. Adult fish can also be affected but to a lesser degree.
