Detailed Description

In the prior SDS-protein electrophoresis, after the electrophoresis gel is prepared, a plurality of narrow grooves can be formed at the upper end of the electrophoresis gel through an electrophoresis comb, the narrow grooves are generally square grooves, the width of each narrow groove is the width of the space between two glass plates, and the length of each narrow groove is slightly longer than the width of each narrow groove. The first type of the suction head is a common suction head, the common suction head is thick, the outer diameter of the common suction head is larger than the width of the narrow groove, the suction head cannot be inserted into the narrow groove, the suction head can only fill sample liquid at the opening at the upper end of the narrow groove, and the sample liquid can be easily filled into the narrow groove beside the suction head, so that the first type of the suction head cannot meet the filling requirement; the second type is that the suction head is a common suction head, the outer diameter of the common suction head is smaller, the common suction head can be inserted into the narrow groove, but the common suction head is thinner, the flowing water of the sample liquid is larger during liquid injection, and the sample liquid is easy to recoil to the narrow groove beside the pollution from the outside from the narrow groove, so the second type of common suction head can not meet the filling requirement.

This application is mainly improved to ordinary suction head application of sample to make ordinary suction head application of sample can not pollute other narrow grooves. The common suction head is thick, and the outer diameter of the common suction head is larger than the width of the narrow groove, so that the common suction head cannot be inserted into the bottom of the narrow groove for sample loading. If the width of the narrow groove can be widened, a common suction head can be inserted into the bottom of the narrow groove, but the electrophoretic gel preparation has certain thickness requirements, so that the width of the narrow groove cannot be directly increased.

Based on above-mentioned analysis, be equipped with the mounting groove at the lateral wall of slot in this application, the mounting groove is located the lateral wall of slot, installation elastic component in the mounting groove, and the elastic component can increase the width of slot through elastic deformation is indirect for when ordinary suction head can insert the bottom of slot through extrusion elastic component and annotate, and then can avoid ordinary suction head to pollute other slots at the upper end entry application of sample. Therefore, the installation groove and the elastic piece are arranged at the corresponding position of the glass plate, so that the requirement of using a common suction head for filling the sample liquid can be met.

The present invention will be described in further detail with reference to the accompanying drawings. Wherein like elements in different embodiments are numbered with like associated elements.
