JP2001249111A - Method for photographing electrophoretic pattern - Google Patents

Abstract

PROBLEM TO BE SOLVED: To stretch a wrap film without wrinkles, for use as gel support during the photography of a gel pattern. SOLUTION: The wrap film is floated above a glass surface or a photographic surface, is stretched over an entire space, and placed on the photographic surface as support for a gel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for supporting an electrophoretic gel on a photographing surface when photographing a pattern of the gel.

[0002]

2. Description of the Related Art When imaging an electrophoresis pattern of a biological sample, a stained electrophoresis gel is directly placed on an imaging surface of an imaging device. However, if the number of times of photographing is increased, a stain solution, gel fragments and the like may remain on the photographing surface, and these may be photographed together.

For this reason, a disposable method in which the direct mounting on the photographing surface is stopped, a transparent so-called home wrap film is laid on the photographing surface every time the photographing is performed, and the gel is placed on the film, and the wrap film is replaced every time the gel photographing is performed. I have been. However, this food packaging film, such as Saran (trade name) wrapping film, can be peeled off but easily sticks when it comes into contact with something, and requires extremely advanced techniques and time to lay it on a glass surface without wrinkles. It takes.

[0004]

SUMMARY OF THE INVENTION According to the present invention, in the above-mentioned disposable system, a method of stretching a wrap film simply and without wrinkles has been developed so that an electrophoresis pattern can be easily photographed.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a transparent wrap film is stretched in a space completely in parallel with a photographing surface which is easy to stick to, without being in contact with the photographing surface, and the wrap film is used as a gel support. Resolve.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a frame 1 for wrapping a wrap film 4 used in carrying out the method of the present invention in a space. Wrap film 4 is placed on the upper surface of a substantially thick square frame.
A sheet of a material (for example, a silicone resin) that adheres well, or a coating or a frame 1
The whole is made of glass. To extend the film 4 over the upper surface of this square frame, first stretch the wrap film on the frame and press the edge onto the attachment surface 2 to attach the film, but if the film surface has slack, remove the appropriate edge. Peel, pull, and press again onto the attachment surface 2.
At this time, the other edges are adhered and fixed and the wrap film 4
Since the surface of the film 4 is not in contact with any part, the wrinkles can be extremely easily spread and the film 4 can be spread.

[0007] The stained electrophoresis gel 5 is placed on the wrap film 4 fixed in such a tensioned state.
The electrophoresis gel imaging apparatus is installed on the imaging surface 6 facing the camera 7 of the electrophoresis gel imaging apparatus as it is, and this pattern is shown in FIG. When the electrophoresis gel 5 is moved and positioned on the wrap film 4 by hand, the gel may be damaged or air bubbles may enter, which is not preferable. Therefore, the wrap film frame 1 itself is gripped by the handle 3 and the photographing surface 6 is held. Move up.

[0008] The film used in the present invention is transparent and elastically stretchable, and can be attached and peeled without any adhesive without any adhesive. For example, generally available wrap film for food packaging is suitable.
