Biotin-PEG2-C6-azide - 98%, high purity , CAS No.1011268-29-3
Basic Description Specifications & Purity 98% Storage Temp Store at -20°C Shipped In Dry ice Product Description Biotin-PEG2-C6-azide is PEG derivative containing a biotin group and an azide group. The azide group can react with either alkyne moiety in Cu(I)-catalyzed Click Chemistry reaction or DBCO moiety in copper-free Click Chemistry reaction to form a stable triazole linkage. The spacer arm helps to minimize steric hindrance involved with the binding to avidin molecules.
