Description

一种可手机APP远程控制的全自动western抗体孵育洗膜机A fully automatic western antibody incubation and washing machine that can be remotely controlled by mobile APP

技术领域technical field

本发明属于实验设备制造领域,涉及一种全自动洗涤系统,具体涉及一种可手机APP远程控制的全自动western抗体孵育洗膜机。The invention belongs to the field of experimental equipment manufacturing, and relates to a fully automatic washing system, in particular to a fully automatic western antibody incubation and washing machine which can be remotely controlled by a mobile APP.

背景技术Background technique

在生命科学、生物医学及农林科学科学研究中及生产领域,蛋白质印迹法(免疫印迹试验)即Western Blot,它是分子生物学、生物化学和免疫遗传学中常用的一种实验方法。其基本原理是通过特异性抗体对凝胶电泳处理过的细胞或生物组织样品进行着色。通过分析着色的位置和着色深度获得特定蛋白质在所分析的细胞或组织中表达情况的信息。公知用于检测蛋白质的western-blot实验中经过高电流将蛋白质转印到聚偏二氟乙烯(PVDF)膜,然后使蛋白质与特异性的抗体结合,通过抗体结合-游离抗体洗涤-二抗结合-化学发光等步骤进行检测,该过程中特异性的抗体孵育通常需要在4-8℃进行,时间16-20小时,转印膜的洗涤通常在室温环境中短时间、多次重复洗涤,该过程需要人工反复进行更换抗体或洗涤液,大量耗费时间及人力。目前,市场上出现的western洗膜机是为了适应生命科学等科研实验领域对局部实验操作过程的方便需求而设计的。但是,在实际使用中,由于对实验时间安排的限制等缺点并没有解决western-blot实验中劳动力浪费问题,而且抗体的孵育和洗涤过程未能连续、未能程序化,操作人员必须在一定时间内亲临现场进行操作,且抗体孵育需要将摇床等设备放置在2-8℃冰箱中进行,存在安全隐患,大大限制科学研究中时、空、人协调发展。In the scientific research and production fields of life science, biomedicine and agriculture and forestry science, western blotting (immunoblotting test) is Western Blot, which is an experimental method commonly used in molecular biology, biochemistry and immunogenetics. The basic principle is to stain the cells or biological tissue samples treated by gel electrophoresis through specific antibodies. Information about the expression of specific proteins in the analyzed cells or tissues can be obtained by analyzing the location and depth of staining. In the well-known western-blot experiment for protein detection, the protein is transferred to polyvinylidene fluoride (PVDF) membrane through high current, and then the protein is bound to the specific antibody, through antibody binding-free antibody washing-secondary antibody binding - Detection by chemiluminescence and other steps. In this process, specific antibody incubation usually needs to be carried out at 4-8°C for 16-20 hours. The washing of the transfer membrane is usually repeated at room temperature for a short time. The process requires manual repeated replacement of antibodies or washing solutions, which consumes a lot of time and manpower. At present, the western membrane washing machines appearing on the market are designed to meet the convenience needs of the local experimental operation process in the scientific research and experimental fields such as life sciences. However, in actual use, the problem of labor waste in western-blot experiments has not been solved due to the limitations of the experimental schedule and other shortcomings, and the antibody incubation and washing process is not continuous and cannot be programmed, and the operator must be within a certain period of time. The operation is performed in person at the site, and antibody incubation needs to be carried out by placing shakers and other equipment in a refrigerator at 2-8°C, which poses safety hazards and greatly limits the coordinated development of time, space, and people in scientific research.
