Description
Technical field
The present invention relates to capillary electrophoresis technique fields, are especially applied to the composition of Capillary Electrophoresis.
Background technique
Capillary Electrophoresis is charge species under the action of electric field, the other end is moved to from one end of capillary, using this
The rapidly and efficiently separation of the mixture especially large biological molecule of different charged particles may be implemented in one technology.
The essence of capillary electrophoresis separation charge species is the interaction of power between medium and capillary and separated object,
Its active force mainly includes three aspects: first is that longitudinal electric field driven power, second is that lateral capillary wall adsorption capacity, third is that electric
Longitudinal movement resistance of the swimming medium to separated object matter;Realize that efficiently separating for charge species must shield capillary wall as far as possible
The lateral of separated object matter is adsorbed and allow separated object matter longitudinal movement time enough under electric field force effect;Therefore it selects
Electrophoretic medium must have to capillary tube inner wall and have stronger coating effect to eliminate tube wall to the transverse direction of separated object matter and adsorb,
Reduce electroosmotic flow, increases medium comparative resistance;In terms of qualified sieving media must take into account three above.
Common macromolecule separating medium is polyacrylamide, can with isolation of DNA fragments up to 1200 base numbers, but poly- third
Acrylamide does not have shielding action to capillary wall, it is necessary to add coating in capillary tube inner wall, eliminate capillary tube inner wall to being divided
From large biological molecule absorption and reduce electroosmotic flow, can just efficiently separate large biological molecule especially DNA fragmentation.
