One kind of dynamic capillary coating polymer gel and its preparation method

The invention discloses a capillary tube dynamic coating polymer gel and a preparation method thereof. The preparation method of the capillary electrophoresis sieving medium provided by the invention is to mix a hydrophobic polymer with a hydrophilic polymer in a collosol buffer solution to obtain the sieving medium. The gel prepared by the invention has the ability of dynamic coating on the premise that high resolution is guaranteed, thereby having abilities of both sieving medium and dynamic coating.
