Description:

FITC-PEG-NH2 is one of Ponsure reactive heterobifunctionalgreen fluorescent PEG derivatives. Fluorescein is a bright green fluorescentdye that has excitation/emission wavelength at around ~490 nm/~520 nm.Meanwhile, amine group in this fluorescent PEG molecule can readily react with otheramine reactive groups such as carboxylic acid, aldehyde, succinimidyl NHSester, etc. PEG linker bridged fluorescein and amine group offers better water solubility,flexible linker length and enhanced photostability. Compared to other organicdyes, our PEG fluorescent dyes are brighter and easier to use. These dyes canbe used directly in aqueous solution to label biomolecules without need addingany organic solvents.

Handlingand Use:

FITC-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, visit www.ponsure.com.

StorageConditions：

FITC-PEG-NH2 should bestored at -20℃.Desiccate. Protect from light. Materials may be handled under inert gas forbest stability.
