Description
Technical field
The utility model relates to medical science, particularly relates to a kind of protein chromatographic electrophoresis and retracting device thereof and protein chromatographic electrophoresis and in-situ chemical trace thereof and immune imaging device.
Background technology
Traditional Western Immuno imaging, or claim Western, the polyacrylamide gel electrophoresis comprising albumen is separated, the transfer trace of albumen, the immune detection relying on antigen antibody interaction and protein immunization imaging analysis four important technologies compositions in gel, is protein analysis method the most frequently used in modern life science and clinic study.Tradition Western analyzes to be needed successively to use multiple instrument and equipment, complex operation step, technical requirement is high, the two day time of usual needs just can complete, and cannot realize robotization, and the result obtained usually because of instrument, reagent, method and operator difference and change.Be made up of four complicated technology because traditional Western analyzes, usually need four kinds of instrument and equipments: protein electrophoresis instrument, albumen transferring film instrument, protein immunoblot instrument and protein immunization imager.The wherein polyacrylamide gel electrophoresis complicated operation of albumen, cannot to be imaged on automatic mode first-class compatible with protein delivery trace, protein immunization.So, go back four complex technologys operations that neither one instrument and equipment can complete traditional Western analysis.Form each individual event instrument and equipment situation that traditional Western analyzes as follows: 1) traditional protein electrophoresis apparatus: namely albumen by size, the character such as electric charge separately.Traditional protein electrophoresis has SDS-PAGE vertical electrophoresis apparatus and isoelectric focusing electrophoresis instrument.Wherein SDS-PAGE vertical electrophoresis apparatus is very general, and isoelectric focusing electrophoresis instrument is with solid phase isoelectric focusing adhesive tape (IPG) electrophoresis system of U.S. Bio-rad Bole and U.S. Thermo thermoelectricity, and the offgel Liquid isoelectric focusing electrophoresis apparatus of Agilent Agilent is main.The critical defect of these two kinds of electrophoresis is all SDS-PAGE vertical electrophoresis apparatus, owing to using polyacrylamide gel medium, all cannot accomplish full-automation; All isoelectric focusing electrophoresises, owing to using IPG adhesive tape, all cannot realize real time imagery.2) namely albumen transferring film instrument is transferred to the albumen in polyacrylamide gel on nitrocellulose filter or PVDF film by its distribution exactly, forms Western blot.Although the transfer liquid that a lot of professional person still continues to use traditional-handwork inhales profit method, electrophoretic transfer is widely used.Electrophoretic transfer must use protein delivery trace instrument.The market of current protein electrophoresis transfer instrument is more chaotic, does not have quality standard.3) protein immunoblot instrument: namely complete antigen antibody interaction on nitrocellulose filter or PVDF film.Owing to will use two kinds of antibody, and will complete protection and the washing of film repeatedly, automation process is more loaded down with trivial details.But process is loaded down with trivial details just, people are very high to the demand of robotization.Over the years, full-automatic protein immunoblot instrument is proposed both at home and abroad respectively.The XD236 automatic westem blot instrument that the B20 type full-automatic Western blotting instrument of such as Britain Bee Robotics, ProfiBlot48, AutoBlot36 of U.S. TECAN and domestic upper Hisoon reach.But due to expensive, it is not very general for using.4) immune imaging instrument: namely nitrocellulose filter or PVDF film developing the color with the interactional albumen of antibody and in situ imaging.According to the difference of antibody labeling method with colour developing principle, immune imaging instrument can be divided into chemiluminescence imaging instrument and phosphorimager.Wherein, with the Odyssey near-infrared laser imager of LICOR, the typhoon Multifunction fluorescent scanner of THERMO and the LAS-4000 fluorescence of FUJI and chemiluminescence imaging instrument for representative.At present, mainly based on import equipment.So, first tradition Western analyzes exists a lot of problem, and traditional Western analyzes to be needed successively to use multiple instrument and equipment, complex operation step, and technical requirement is high, the two day time of usual needs just can complete whole analysis, is unable to catch up with the paces of Development of Modern Science; And the result that traditional Western analyzes usually changes because of the difference of instrument, reagent, method and operator, can not meet the requirement to protein quantification in biomedicine; Four technology ingredients that tradition Western analyzes cannot be compatible on automatic mode, goes back all processes that neither one instrument and equipment can complete traditional Western analysis at present; Finally, Western analytical approach has demand widely clinically, but present operation is all open, and cannot avoid operating personnel and the contact detecting sample, clinical position may be subject to the threat of infectiousness sample.
Be electrophoretic medium with polyacrylamide gel in analyzing relative to traditional Western, Capillary Electrophoresis is is split tunnel with kapillary, take free solution as the trace of albumin separation method of medium.Usually, Capillary Electrophoresis uses elasticity (polyimide) the coating fused quartz kapillary that internal diameter is 25-100 μm, except electrophoretic buffer, does not need solid dielectric.So volume is little, rapid heat dissipation, can bear high electric field (100-1000 V/cm), easily realize robotization.Recently, the full-automatic protein immunization analytical instrument based on Capillary Electrophoresis is come out, and the albumen Western that can complete trace, even tens cells analyzes.The advantage that Capillary Electrophoresis protein immunization is analyzed: 1) efficient, plate number is between 105-107 sheet/m; 2) quick, generally in tens minutes, complete separation; 3) trace, the sample volume needed for sample introduction is for receiving upgrading; 4) robotization is the separation method that current automaticity is higher.The shortcoming of Capillary Electrophoresis protein immunization analysis is 1) because sample size is few, thus preparative capacibility is poor, when particularly needing further mass spectrophotometry, often cannot reach required amount; 2) because capillary diameter is little, make light path too short, detect or image sensitivity lower (as ultraviolet absorption spectroscopy); 3) because electroosmosis is different because of sample composition, the poor reproducibility of Protein Separation; 4) instrument and equipment is expensive, and special kapillary consumables cost is too high, limits applying of it.Under contrast, the advantage that traditional Western analyzes just Capillary Electrophoresis protein immunization analytic system lacks, and the advantage of Capillary Electrophoresis protein immunization analytic system just traditional Western to analyze not available for.So optimal system in conjunction with both advantages, should overcome both shortcomings simultaneously.
