Peptide Condensation Reagents and Linkers

Within its comprehensive Novabiochem® product line, Merck offers one of the most extensive ranges of high-quality coupling reagents for in situ activation on the market. Moreover, we provide additives, linkers for solid phase synthesis, and various reagents for the introduction of protecting groups. Thus you can be sure to find the right reagents even for your most demanding applications.

However, with such a plethora of reagents available, the choice of the optimum coupling reagent for a particular application is not always straightforward. Condensation reagents vary in terms of coupling efficiency, stability, solubility, or reactivity of active species (see table below). For example, PyOxim combines high reactivity and solubility with moderate stability, making it an excellent choice for synthesizers employing closed-bottle reagent storage.

In order to help you choosing the appropriate reagent for your individual application, we have prepared for you the technical brochure “Coupling reagents for peptide synthesis” with valuable information on our coupling reagents and detailed methods and protocols (to download the brochure click on the banner on the right).
