Title (EN) NEW ACRYLAMIDO DERIVATIVES AND NEW FORMULATIONS FOR POLYACRYLAMIDE MATRICES IN ELECTROPHORETIC AND CHROMATOGRAPHIC TECHNIQUES
(FR) NOUVEAUX DERIVES ACRYLAMIDO ET FORMULATIONS NOUVELLES DE MATRICES POLYACRYLAMIDES DANS DES TECHNIQUES D'ELECTROPHORESE ET DE CHROMATOGRAPHIE
Abstract:
(EN) New polyacrylamide matrices, based on new acrylamide of formula (I) in which R represents hydrogen or CH3 and R1 and R2, independently between them, represent hydrogen, or a group of the formula -[(CH2)nO]p-H, where n=3 or > 3 and p=1-5, preferably 1, with the proviso that at least one, between R1 and R2, should be different from hydrogen, are described. Such matrices present the following advantages: a) a marked resistance to alkaline hydrolysis (i.e. at the typical pH values of zone electrophoresis); b) a high hydrophilicity; c) a higher porosity, due to the higher Mr values of the monomers.
(FR) On décrit des nouvelles matrices polyacrylamides, à base du nouvel acrylamide de formule (I) dans laquelle R représente hydrogène ou CH3, et R1 et R2 représentent indépendamment l'un de l'autre hydrogène ou un groupe de la formule -[(CH2)nO]p-H, où n=3 ou > 3, et p=1-5, de préférence 1, à la condition que l'un au moins parmi R1 et R2 ne soit pas hydrogène. De telles matrices présentent les avantages suivants: a) une résistance prononcée à l'hydrolyse alcaline (c'est-à-dire au niveau des valeurs de pH typiques de l'électrophorèse de zone); b) une hydrophilie élevée; c) une porosité supérieure, résultant de valeurs plus élevées de masse moléculaire relative des monomères.
