ChemMatrix®

 - The 100% PEG Matrix


Chemical structure of Aminomethyl-ChemMatrix Matrix Innovation has developed a new patented 100% PEG resin that offers a tremendous advantage over polystyrene resin for long and difficult peptides. With its highly crosslinked matrix it has unsurpassed mechanical and thermal stabilities. Let us present to you ChemMatrix® the 100% PEG matrix.

- Higher chemical stability

ChemMatrix® is made exclusively from primary ether bonds which are known to be highly chemically stable. This matrix is therefore much more stable than any other commercial amphiphilic resins.

- Higher loadings

The standard loadings of commercial amphiphilic resins are mainly from 0,2 up to 0,4 mmol/g. With even a better amphiphilicity ChemMatrix® has loadings between 0.8 to 1.0 mmol/g, which is up to 3 times the loadings of other PEG resins.

- Purer crude products

ChemMatrix resin has been compared to polystyrene resin for the synthesis of many difficult peptides and the results cleary demonstrate a huge advantage in using it. Results are shown in the following pages.

- Free flowing

ChemMatrix® is a user friendly resin because it is delivered as free flowing powder. It is easily weighted and transfered with minimum losses on glassware.

- Higher compatibility with solvents

ChemMatrix® allows the use of almost any kind of solvent, even water. The standard solvents used for polystyrene, such as dichloromethane and THF, are also very compatible with ChemMatrix®. Some amphiphilic resins are known to have a good swelling, but the loading and/or the mechanical stability are affected. Usually, these resins become tacky and hard to handle once solvated. You will be surprised to see how ChemMatrix® is easily filtered and washed with almost any solvents.
