Title:
METHOD FOR ANALYSIS OF SAMPLE BY CAPILLARY ELECTROPHORESIS
Document Type and Number:
WIPO Patent Application WO/2008/029684
Kind Code:
A1
Abstract:
Disclosed is an analysis method by capillary electrophoresis, which enables the
size reduction of an apparatus, shows a high analysis accuracy, and can be carried
out readily. Specifically disclosed is a method for analysis of a sample by capillary
electrophoresis, comprising the steps of: providing a capillary tube for use
in the capillary electrophoresis; and performing the electrophoresis of a complex
of the sample and a compound having a cathodic group in the capillary tube, wherein
the capillary tube has a layer A laminated on the inner wall and a layer B laminated
on the layer A: layer A: an interlayer composed of at least one member selected
from polydiallyldimethylammonium chloride, a non-polar polymer and a compound
having an anodic group, wherein polydiallyldimethylammonium chloride is immobilized
on the inner wall by means of physical adsorption, or at least one of the non-polar
polymer and the compound having an anodic group is immobilized on the inner wall
by means of a covalent bond; and layer B: a cathodic layer composed of a compound
having a cathodic group.
