Title (EN) METHOD FOR THE PREPARATION OF A MEMBRANE LINED WITH A GEL LAYER AND FRAME FOR THE SUPPORT OF SUCH MEMBRANE TO IMPLEMENT SUCH METHOD
(FR) PROCEDE DE PREPARATION D'UNE MEMBRANE GARNIE D'UNE COUCHE D'UN GEL ET CADRE DE SUPPORT D'UNE TELLE MEMBRANE CONÇU POUR LA MISE EN ×UVRE DE CE PROCEDE
Abstract:
(EN) The frame is comprised of two small bars (1, 2) braced by two pairs of elastic blades (3,4) and (5, 6). Cams (11, 12) bias said blades to bring the small bars (1, 2) closer to each other. The membrane is then fixed under the bars (1, 2) and a gel is cast on the membrane. The cams are brought to a position wherein they stop biasing the elastic blades thereby allowing the small bars (1, 2) to move apart from each other while tensioning the membrane supporting the gel. Application to the preparation of gel/membrane assemblies for making electrophoretic migration spectra of macromolecules.
(FR) Le cadre comprend deux barrettes (1, 2) entretoisées par deux paires de lames élastiques (3, 4) et (5, 6). Des cames (11, 12) chargent ces lames pour rapprocher les barrettes (1, 2) l'une de l'autre. La membrane est alors fixée sous les barrettes (1, 2) et un gel coulé sur la membrane. Les cames sont amenées dans une position où elles cessent de charger les lames élastiques ce qui a pour effet de permettre aux barrettes (1, 2) de s'écarter l'une de l'autre en tendant la membrane de support du gel. Application à la préparation d'ensembles gel/membrane pour la réalisation de spectres de migration électrophorétique de macromolécules.
