Appearance: Pink/darkred solid. Solubility: 5mg/mL, in chloroform,DMSO. Stability: 1 Years at-20°C, Desiccate.Protect from light. Ex/Emwavelength: 544 nm/576 nm. MolecularWeight（PEG）: 1K,2K,3.4K,5K,10K. Reactivegroup: Amine (-NH2). Description: RB-PEG-NH2 is one of heterobifunctional redfluorescent PEG dye that contains a terminal rhodamine B dye and a primaryamine group on each PEG terminus. Rhodamine B is a bright red fluorescent dyewith excitation/emission wavelength at around ~544 nm/~576 nm. Aminefunctionalized Rhodamine PEG can be used to react with other moleculescontaining amine reactive groups such as NHS, COOH, etc. PEG linker bridgedRhoamine and amine group offers better water solubility, flexible linker structureand enhanced stability. Compared to other organic dyes. Handlingand Use: RB-PEG-NH2 is sensitive to light and temperature. Forbest use, material should always be kept in low temperature in dry condition.Protect from light. Avoid frequent thaw and freezing. For moreinformation about using this product, StorageConditions： RB-PEG-NH2 should be stored at -20℃.Desiccate. Protect from light. Materials may be handled under inert gas forbest stability.
