Voltage control device of protein isoelectric focusing and voltage control method thereof

Abstract

The invention discloses a voltage control device of protein isoelectric focusing which comprises a controller, a visualization interface, a semiconductor cooling platform and a high throughput electrophoresis platform, wherein the visualization interface, the semiconductor cooling platform and the high throughput electrophoresis platform are electrically and respectively connected with the controller; the controller comprises a signal recognizer, a control chip, a modulus converter, an analog converter, and a high voltage regulation mechanism, wherein the signal recognizer transmits a voltagecontrol signal to the modulus converter; the voltage control signal is processed by the control chip, converted by the analog converter and regulated by the high voltage regulation mechanism, and thevoltage is transmitted to the visualization interface and is feedback to the signal recognizer. The high voltage output by a voltage control mechanism disclosed by the invention is stable, the visualization interface adopted not only can keep track of the operation process of the protein isoelectric focusing, but also allows a user to modify directly on the visualization interface or set high voltage value of amplitude and select a voltage building up method, and the operation is simple, convenient and humanized.

Description

technical field [0001] The invention relates to a voltage control device for protein isoelectric focusing and a voltage control method thereof. Background technique [0002] The basic completion of the Human Genome Sequencing Project announced that life science research has entered the era of post-genomics with "proteomics" research as the core. Proteomics is a science that takes the proteome as the research object and analyzes the protein composition and activity rules of an organism, cell or tissue at the overall level. Protein is the executor of physiological functions and the direct embodiment of life phenomena. The study of protein structure and function can directly clarify the change mechanism of life under physiological or pathological conditions. The study of proteomics provides a precise and detailed molecular description of the condition of a cell or tissue. At present, proteomics research has become one of the most effective research methods to find disease mol...

Problems solved by technology

However, the control mechanism of the current automatic isoelectric focusing instrument for protein separation is complex and inefficient, the high-voltage voltage control is not accurate, and the temperature control is unstable; and the interface setting is simple, which is extremely inconvenient to use, and it is cumbersome for users to modify or set control parameters. Only after training can master the operation skills
