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.

MAL-PEG6-TFP ester serves as a bifunctional PEG linker comprised of a maleimide group, which is reactive with thiols between pH 6.5 and 7.5, and TFP ester, which can react with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilic PEG6 chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG4-TFP ester constitutes a heterobifunctional PEG linker with an azide group that participates with copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN. The water solubility of the compound is improved by the PEG chain. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG12-TFP ester represents a heterobifunctional PEG linker containing an azido group that reacts with alkynes, DBCO, and BCN via copper-catalyzed Click Chemistry, while the TFP ester reacts with primary amines and is more hydrolysis-resistant than NHS ester. The hydrophilicity of the compound is enhanced by the PEG linker. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Azido-PEG24-TFP ester acts as a heterobifunctional PEG linker possessing an azido for copper-catalyzed click reactions with alkynes, DBCO, and BCN. TFP ester reacts with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilicity of the molecule is bolstered by the PEG24 units.
