Abstract

Matrici da impiegarsi in metodiche elettrocinetiche, a base di monomeri di acrilamide mono- e disostituite sull'azoto amidico (per esempio, dimetil acrilamide, acriloil-morfolina, trisacril) presentano i vantaggi a) di una spiccata resistenza all'idrolisi a pH alcalini (tipici dell'elettroforesi zonale); b) di una buona idrofilicità; c) di una più elevata porosità, dovuta all'aumentato Mr dei monomeri. E' inoltre possibile aumentare la porosità del gel polimerizzandolo in presenza di agenti di aggregazione laterale delle catene (per esempio, glicol polietilenico ad Mr 6.000-20.000 Da), con ottenimento di matrici che permettono una migliore risoluzione di proteine ad Mr elevato e di frammenti di acidi nucleici; polimerizzando la matrice in presenza di un gradiente di agente aggregante, si ottiene un gradiente di porosità anche con quantità costanti di monomeri nel gel. Infine, la fotopolimerizzazione (per esempio con riboflavina e luce) anziché con catalizzatori red/ox evita la formazione di N-ossidi di amine presenti nella soluzione di partenza.
