应用简介: Biotin functionalized polyethylene glycol (PEG-Biotin) is an avidin or streptavidin binding PEG derivative that is used to biotinylate biomolecules or other material surfaces. Biotin can be easily detected by biotin/streptavidin binding assay and is widely used for molecule target detection. 罗丹明B荧光标记的聚乙二醇是芃硕生物(Ponsure)荧光标记PEG衍生物中的一种。(RB-PEG)吸收波长570 nm,发射波长约595 nm。罗丹明B可以很容易追踪粉红色和红色荧光。
