Synonym: Biotin PEG2 amine, Biotin-PEG2-NH2, NH2-PEG2-Biotin, Amino PEG2 Biotin Description: Biotin PEG2 Amine (Biotin-PEG2-NH2) is one of Nanocs discrete Biotin PEG derivatives that have 2 PEG units (diethylene glycol) between biotin and amine group. Biotin is a commonly used labeling tag in bioassays that can bind to avidin or streptavidin with high affinity. Amino group in this molecule can be used to react with other functional groups such as NHS, -COOH, etc. to attach biotin tag to other molecules or material surfaces. PEG linker between biotin and amine offers better water solubility, reduced steric hindrance and enhanced reactivity. Product Specifications: Form: Solid Color: Water Solubility: Soluble in DMSO Functional group: Biotin Binding target: Avidin or streptavidin Reactive group: NH2 Reactive to: NHS, -COOH, etc. Applications: Biotinylation  Storage: Store at -20 0C.
