WebAug 19, 2024 · Fugier et al. used a copper-free click reaction to detect bacteria at low concentrations. Image source: PLOS One. A Brief Protocol Involving SPAAC Bioconjugation. In the following steps, we briefly describe a step-by-step method involving SPAAC for the application of creating a shorter immuno-PCR method. You can find the … WebCopper-free click reaction with cyclooctyne. Cyclooctyne, the smallest isolable cycloalkyne, is able to undergo azide-alkyne Huisgen cycloaddition under mild, physiological conditions in the absence of a copper(I) catalyst due to strain. This reaction has found widespread application as a bioorthogonal transformation for live cell imaging. headbands with tails
