Description

Diaphragm cutting device

Technical Field

The utility model relates to a cutting tool, in particular to diaphragm cutting device.

Background

Western blotting, also known as immunoblotting, is known in English under the name Western Blot. Western blotting is a common experimental procedure used in molecular biology, biochemistry, basic medicine and immunogenetics. The basic principle is to stain a gel electrophoresis treated cell or biological tissue sample with a specific antibody. Information on the expression of a specific protein in the analyzed cell or tissue is obtained by analyzing the location and depth of staining. In the experiment, in order to enable the specific antibody to effectively recognize the specific protein, the total protein needs to be transferred from the separation gel through a membrane transferring step and fixed on a PVDF (polyvinylidene fluoride) membrane, and meanwhile, in order to ensure the success of membrane transferring, an experimental operator needs to cut the PVDF membrane into an appropriate rectangular size according to the size of the separation gel. Currently, a paper cutter is mostly used in a laboratory to cut the PVDF membrane; however, the guillotine is dangerous to use, and can cut the fingers of the operator carelessly, which is harmful to health and affects the experiment progress and efficiency. In addition, when the membrane is transferred, the PVDF membrane and the separation gel are attached together in a face-to-face manner, and when the membrane is transferred, because the protein is fixed on the PVDF membrane in a colorless state, if an operator forgets to mark the PVDF membrane in advance, the direction or the front side and the back side of the PVDF membrane are often unclear, so that the subsequent immunoblotting test is influenced.
