Description: VUN 00880, also known as Carboxyrhodamine 110PEG4-DBCO is a PEG derivative containing a DBCO group and a rhodamine dye. DBCO enables copper free Click Chemistry and will react with azide-bearing compounds or biomolecules to form a stable triazole linkage. This reagent will be an ideal alternative to copper intolerant applications and can be used to label cells, tissues, biomarkers or nanoparticles. This product has not formal name. For the convenience of scientific communication, we named it by combining its Inchi key (3 letters from the first letter of each section) with the last 5 digits of its CAS number or its molecule weight if its CAS number is not available (see MedKoo Chemical Nomenclature,
