Patent

CA 2549926

The present invention relates to a novel use of a positively charged support, namely as a sample loading support for loading samples onto an IPG (Immobilised pH gradient) gel. The support or paper is provided with positively charged groups, such as cation groups, and is used to load samples from the cathode side of the IPG gel. Furthermore, the invention relates to a kit comprising a positively charged sample application support as above and an IPG gel, preferably a pre-swollen RTG gel comprising an acidic pH-interval.

L'invention concerne une nouvelle utilisation d'un support chargé positivement, plus spécifiquement un support de charge d'échantillon destiné à charger des échantillons sur un gel IPG (gradient pH immobilisé). Ce support ou papier possède des groupes chargés positivement, tels que des groupes de cations, et est utilisé pour charger des échantillons à partir du côté cathode du gel IPG. En outre, cette invention concerne un kit comprenant un support d'application d'échantillon chargé positivement tel que décrit ci-dessus et un gel IPG, de préférence un gel RTG pré-gonflé comprenant un intervalle pH acide.
