Abstract
(EN)
Provided herein are sulfo n-hydroxysuccimidyl ester (sulfo-SE) linked peptides, methods of synthesis thereof, and methods of using such peptides for labeling of biomolecules. In particular, peptides comprising non-alkyl group such as serine, threonine, cysteine, tyrosine, glutamic acid, and aspartic acid are stably modified (e.g., without autoreactivity) with a sulfo-SE group and used to label or otherwise modify biomolecules.
(FR)
L'invention concerne des peptides liés à un ester sulfo n-hydroxysuccimidyle (sulfo-SE), leurs méthodes de synthèse, et des méthodes d'utilisation de tels peptides pour un marquage de biomolécules. L'invention concerne en particulier des peptides comprenant un groupe non alkyle tel que la sérine, la thréonine, la cystéine, la tyrosine, l'acide glutamique et l'acide aspartique sont modifiés de manière stable (par exemple, sans autoréactivité) avec un groupe sulfo-SE et servent à marquer ou autrement modifier des biomolécules.
