Description:
N3-PEG-NH2 is one of Click Chemistry PEG reagents that contain a terminal azide and amine group on each PEG terminus. Azide group reacts readily with linear alkyne group catalyzed by cooper catalyst. It can also react directly with strained alkyne molecules such as DBCO without need any catalyst. Meanwhile, amine groups can be used to react with a number of amine reactive groups such as carboxylic acids, succinimidyNHS ester, aldehydes and many others. PEG linker between azide and amine group offers better water solubility, less steric hindrance and enhanced stability. Compared to other Click chemistry reagents,Azido PEG amines are soluble in water and alreactions can be carried out in aqueous buffer without need any organic solvents.
Handling and Use:
N3-PEG-NH2  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition.
 Avoid frequent thaw and freezing. For more information about using this product, visit www..com.
Storage Conditions：
N3-PEG-NH2 should be stored at-20℃. Desiccate.  Materials may be handled under inert gas for best stability. Re-test material after12 months.
