Contact with the buffer liquid above the gel plate, the underside of the mold plate being arranged to, together with the bearing surface of the support plate, give the intermediate buffer liquid body a predetermined shape between the electrodes.
FIGURBESKRIVNING Uppfinningen beskrivas närmare nedan under hänvisning till bifogade ritning, på vilken den enda figuren visar en tvärsektionsvy av en utföringsform av en elektrofores- kammare enligt uppfinningenr BESKRIVNING AV UTFÖRINGSFORM I figuren visas en tvärsektionsvy av en utföringsform av en elektroforeskammare enligt uppfinningen. Den generellt med l betecknade elektroforeskammaren, som antages vara rektangulär innefattar på i och för.sig känt sätt änd- väggar 2, sidoväggar 3, varav endast den ena visas, samt en bottenplatta 4, vilka samtliga består av ett elektriskt isolerande material, exempelvis plexiglas. Längs insidan av ändväggarna 2 förefinnes på i och för sig känt sätt elektroder 5, vilka är anslutna till var sin pol av en elektrisk likspänningskälla 6. Éottenplattan 4 fungerar vid den visade utföringsformen som bärplatta för en gelplatta 7 av konventionell, parallellepipedisk.form. Denna gelplatta 7 är avsedd att fungera som separationsmedium för separation av partiklar i på gelplattan 7 anbragta, icke visade prov. Elektrofores- kammaren 1 är på i och för sig känt sätt fylld med en i och för sig känd buffertvätska 8 till sådan nivå att gelplattan 7 är fullständigt täckt. Vid den visade utföringsformen kommer partiklarna på känt sätt att uppdelas i band i plattan 7 mellan elektroderna 5. 45* 431..DESCRIPTION OF THE DRAWINGS The invention is described in more detail below with reference to the accompanying drawing, in which the single figure shows a cross-sectional view of an embodiment of an electrophoresis chamber according to the invention. DESCRIPTION OF EMBODIMENT The figure shows a cross-sectional view of an embodiment of an electrophoresis chamber. The electrophoresis chamber generally designated 1, which is assumed to be rectangular, comprises in a manner known per se end walls 2, side walls 3, of which only one is shown, and a bottom plate 4, all of which consist of an electrically insulating material, for example plexiglass . Along the inside of the end walls 2 there are electrodes 5 in a manner known per se, which are connected to their respective poles by an electrical direct voltage source 6. In the embodiment shown, the octane plate 4 functions as a support plate for a gel plate 7 of conventional, parallelepipedic shape. This gel plate 7 is intended to function as a separation medium for separation of particles in samples (not shown) applied to the gel plate 7. The electrophoresis chamber 1 is in a manner known per se filled with a buffer liquid 8 known per se to such a level that the gel plate 7 is completely covered. In the embodiment shown, the particles will be divided in a known manner into bands in the plate 7 between the electrodes 5. 45 * 431 ..
För att vid denna konventionella, parallellepipediska gel- platta 7 erhålla samma förhållanden som vid exempelvis 10 15 , 20 25 30 449 929' 'a olinjärt kilformade geler används enligt uppfinningen en formplatta 9 av elektriskt isolerande material, som med sin undersida bringas i kontakt med buffertvätskan 8 ovanför gelplattan 7, Formplattan 9 hålls vid den visade utföringsformen på plats med hjälp av handtag 10, som är lösbart fästa,exempe1vis med hjälp av någon i och för sig känd, icke visad låsanordning, vid respektive ändväggs 2 överkant. vid den visade utföringsformen är undersidan av formplattan 9 utformad att tillsammans med bottenplattan 4 ge buffertvätskekroppen en olinjär kilform i separatione- riktningen mellan elektroderna 5. Formplattans 9 undersida är således utformad att divergera från bottenplattan 4.1 riktning från den vänstra till den högra elektroden 5.In order to obtain in this conventional, parallelepipedic gel plate 7 the same conditions as in, for example, non-linear wedge-shaped gels, a mold plate 9 of electrically insulating material is used according to the invention, which is brought into contact with its underside with the buffer liquid 8 above the gel plate 7, The mold plate 9 is held in place in the illustrated embodiment by means of handles 10, which are releasably attached, for example by means of a per se known, not shown locking device, at the upper edge of the respective end wall 2. in the embodiment shown, the underside of the mold plate 9 is designed to together with the bottom plate 4 give the buffer liquid body an non-linear wedge shape in the separation direction between the electrodes 5. The underside of the mold plate 9 is thus designed to diverge from the bottom plate 4.1 from the left to the right electrode 5.
Samma förhållanden kommer härvid att råda i den av gel- plattan 7 och buffertvätskekroppen mellan bottenplattan 4 och formplattan 9 bildade kroppen som i en olinjärt kil- formad, homogen gelkropp mellan bottenplattan 4 och formplattan 9. I Formplattans 9 undersida behöver givetvis icke divergera olinjärt från bottenplattan 4, utan kan i stället divergera linjärt frân.bottenplattan 4 till bildande av en linjärt kilformad buffertvätskekropp.The same conditions will prevail in the body formed by the gel plate 7 and the buffer liquid body between the base plate 4 and the mold plate 9 as in a non-linear wedge-shaped, homogeneous gel body between the base plate 4 and the mold plate 9. In the underside of the mold plate 9, of course, divergent need not diverge from the bottom plate 4, but can instead diverge linearly from the bottom plate 4 to form a linear wedge-shaped buffer liquid body.
I vissa tillämpningar kan det även vara önskvärt att form- plattans 9 undersida sträcker sig parallellt med botten- plattan 4 mellan elektroderna 5 till bildande av en parallell- epipedisk vätskekropp. Härigenom kan den använda buffert- vätskans 8 volym minskas särskilt i de fall när buffertvätskan måste cirkuleras för att motverka värmeutvecklingen i en gel, där hög spänning används mellan elektroderna 5. I dessa fall kommer formplattan 9 även att förhindra att buffert- vätskevâgor bildas ovanför gelplattan 7, vilka vågor momen- tant skulle förändra den elektriska fältstyrkan på de ställen, där de uppträder. ._ ._...._.... an...In some applications it may also be desirable for the underside of the mold plate 9 to extend parallel to the bottom plate 4 between the electrodes 5 to form a parallelepipedic liquid body. As a result, the volume of the buffer liquid 8 used can be reduced, especially in cases where the buffer liquid must be circulated to counteract the heat development in a gel, where high voltage is used between the electrodes 5. In these cases the mold plate 9 will also prevent buffer liquid waves from forming above the gel plate. 7, which waves would momentarily change the electric field strength at the places where they occur. ._ ._...._.... an ...
