Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of incubation instruments, and in particular relates to a membrane washing and incubation integrated machine with refrigeration. Background Art
[0002] Western, also known as Western blotting, Western blotting, and Western blotting, is one of the important methods for detecting proteins with antibodies. In molecular biology, biochemistry, and immunogenetics research, protein blotting (immunoblotting test) is a commonly used experimental method. Its basic principle is to stain cells or biological tissue samples treated with gel electrophoresis with specific antibodies. By analyzing the position and depth of staining, information on the expression of specific proteins in the analyzed cells or tissues is obtained. The Western blotting method uses polyacrylamide gel electrophoresis, the object to be detected is protein, the "probe" is antibody, and the "color development" uses labeled secondary antibodies. The protein sample separated by PAGE (polyacrylamide gel electrophoresis) is transferred to a solid phase carrier (such as nitrocellulose membrane), which adsorbs the protein in the form of non-covalent bonds and can keep the type of polypeptide separated by electrophoresis and its biological activity unchanged. The protein or polypeptide on the solid phase carrier is used as an antigen to react with the corresponding antibody, and then react with the enzyme or isotope-labeled second antibody. The protein components expressed by the specific target gene separated by electrophoresis are detected through substrate color development or radioautography. This technology is also widely used to detect the expression of protein levels.
[0003] The experimental steps of Western Blot include electrophoresis, transfer, blocking, first membrane wash, incubation with primary antibody, second membrane wash, incubation with secondary antibody, third membrane wash, and color development. The conventional practice is to wash the membrane three times, each wash lasting 10 minutes. Depending on the experimental needs, the washing time may sometimes be longer. The first and second membrane washes do not require protection from light, and the third membrane wash may or may not be protected from light depending on the color development method.
[0004] Currently, Western Blot experiments are usually performed manually, requiring manual addition of sample liquid. After the experiment, the experimental reagents must be manually poured out and manually cleaned. The entire process is very cumbersome and inconvenient, with a low degree of automation and high workload for experimenters. If any operation goes wrong, the operation must be restarted, which is very time-consuming. In addition, due to incomplete manual operation, residual liquid or uneven sample addition may occur. For some products with non-replaceable gun tips, there is a possibility of cross-contamination during the process of aspirating multiple reagents, resulting in inaccurate experimental data.
