Propargyl-PEG7-NHS ester contains a propargyl group and an NHS ester. As an amine reactive reagent, this product can be used for derivatizing peptides, antibodies, amine coated surfaces etc. In the presence of copper catalyst, propargyl group reacts with azide to yield a stable triazole linkage. The PEG units help increase the hydrophilicity of the reagent. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Isocitrate Dehydrogenase 1 (IDH1) is a soluble, cytosolic enzyme involved in the TCA metabolic cycle. The most notable mutation in this enzyme, R132H, is clinically indicated in the majority of astrocytomas and oligodendroglial tumours, with the mutation being associated with more favourable prognosis and increased survival in those patients. IDH1 R132H is also useful in the differential diagnosis between anaplastic glioma and glioblastoma.
