Propargyl-PEG2-acid is a linker consisting of propargyl and carboxylic acid functional groups. In the presence of activators (e.g. EDC, or HATU), the carboxylic acid reacts with primary amine to form a stable amide bond. The propargyl group reacts with azide group in biomolecules to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Tumor-Associated Glycoprotein 72 (TAG-72) is a glycoprotein found on the surface of many cancer pathologies. Anti-TAG-72 can be useful for detecting some adenocarcinomas and non-neoplastic tissues. This diagnostic grade TAG-72 IVD antibody is useful for identifying adenocarcinomas in positive staining, but in mesotheliomas no staining is observed.
