PROBLEM TO BE SOLVED: To provide a sample introducing method by which separation of a biological sample by isoelectric point electrophoresis can be readily accomplished with high reproducibility.SOLUTION: A sample introducing method by which a biological sample is introduced into a sample separation medium 42 that separates the biological sample by electrophoresis comprises: a first step of supplying a sample solution S to a sample holder 3 of an electrophoretic chamber 1 having an installation face 1a, on which the sample separation medium 42 is to be installed, and a first electrode 30 and a second electrode 31 connected to two ends of the sample separation medium 42, the installation face 1a being provided with the sample holder 3 that holds the sample solution S containing the biological sample while restraining expansion of wetting by the sample solution S; and a second step of bringing the sample solution S supplied to the sample holder 3 into contact with the sample separation medium 42 and introducing the biological sample into the sample separation medium 42. |
