產品簡介:The red-fluorescent tetramethylrhodamine alkyne can be reacted with azides via a copper-catalyzed click reaction. Click chemistry describes a class of chemical reactions that use bio-orthogonal or biologically unique moities to label and detect a molecule of interest using a two-step procedure. The two-step reaction procedure involves a copper-catalyzed triazole formation of an azide and an alkyne. Click reactions have several characteristics: the reaction between the detection moieties is efficient; no extreme temperatures or solvents are required; the reaction product is stable; the components of the reaction are bioinert; and perhaps most importantly, no side reactions occur – the label and detection tags react selectively and specifically with one another. Unlike traditional chemical reactions utilizing succinimidyl esters or maleimides that target amines and sulfhydryls – functional groups that are not unique – click chemistry-labeled molecules can be applied to complex biological samples and be detected with unprecedented sensitivity due to extremely low background.

小分子PEG是指PEG以2個或2個以上的重復單元相連接而成，他們不同于高分子PEG，他們的分子量都是固定值，而分子量的大小跟重復單元相關，重復單元越高，分子量越大，因為他們不是高分子聚合物的PEG，而是一種小分子的重復單元PEG衍生物，因此他們常常是一種純的小分子PEG產品，可以用純度和CAS號來標識他們。
