Lipids & Polymers

SPDP-C6-Gly-Leu-NHS ester Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Biotin-PEG7-thiourea is reactive with amine-containing macromolecule. The hydrophilic PEG arm improves water solubility. The biotin groups serve as an affinity label towards the proteins avidin and streptavidin. The thiourea group can be used as a source of sulfide, such as for converting alkyl halides to thiols. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Azido-PEG3)-N-bis(PEG4-t-butyl ester) is a branched conjugation reagent with a terminal azide group. The azide group enables PEGylation via Click Chemistry. The t-butyl protected carboxyl groups can be deprotected under mild acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Amino-PEG3)-N-bis(PEG4-t-butyl ester) is a PEG linker that can easily react with activated NHS esters or carboxylic acid in the presence of EDC or HATU. The t-butyl group can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

DBCO-PEG2-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

m-PEG-NHS ester, MW 10,000 is an active ester PEG polymer. Coupling between NHS and -NH2 is used for PEGylation, protein labeling, surface modification, therapeutic nanocarrier etc. Reagent grade, for research purpose.
