DBCO-PEG36-TFP ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The hydrophilic PEG spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary azide-containing molecules. The TFP ester is less susceptible to undergo hydrolysis compared to the NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
