Description

A kind of assembly line biological chips sample application platform
Technical field
The utility model relates to the preparation of micro-array biochip, more precisely, relates to the pipelining sample application platform of a kind of many indexs, many person-portions parallel detection usefulness micro-array biochip.
Background technology
Biochip (biochip) is meant methods such as adopting the synthetic or micro-sampling of photoconduction original position, with big molecular proportion of large number of biological such as nucleic acid fragment, peptide molecule even histotomy, biological samples such as cell solidify in holder in an orderly manner (as slide, silicon chip, polyacrylamide gel, carriers such as nylon membrane) surface, form intensive two-dimentional molecules align, then with the molecular hyridization that hits of the biological sample to be measured of mark, intensity of hybridization signal is carried out fast such as laser confocal scanning or electric charge coupling photography camera (CCD) by specific instrument, parallel, check and analysis efficiently, thereby the quantity of target molecule in the judgement sample.Because slide/silicon chip commonly used is as solid support, and in the technology of preparing of preparation process analog computation machine chip, so be referred to as biochip technology.According to the fixing probe difference on the chip, biochip comprises genetic chip, protein-chip, cell chip, organization chip.Owing to can be fixed in extremely a large amount of probes on the holder simultaneously with this technology, so once can carry out check and analysis, thereby solve traditional nucleic acid blot hybridization (Southern Blotting and NorthernBlotting etc.) technical sophistication, automaticity is low, the testing goal molecular amounts is few, small throughput (low through-put) etc. not enough to a large amount of biomolecule.And, by designing different probe arrays, use specific analytical approach can make this technology have multiple different using value, measure as gene expression profile, sudden change detects, polymorphism analysis, genomic library mapping and sequencing by hybridization (Sequencing by hybridization, SBH) etc., for the research of " post genome project " gene function in period and the development of modern medicine science and medical diagnosis provide strong tool, will make the discovery of new gene, gene diagnosis, drug screening, aspects such as administration personalization obtain important breakthrough, change for whole human society brings deeply widely.This technology is cited as one of the 1998 annual worlds, ten big science and technology progress.
The research purpose difference, the chip type difference that expectation is made, the preparation chip method also is not quite similar, and is example with the DNA chip, can be divided into two big classes basically: a class is that original position is synthetic, promptly at support surface direct in-situ synthetic oligonucleotide probe; One class is a directly point sample of pre-synthetic back, and minim DNA solution is directly put and is solidificated on the chip carrier with the form point of microarray.Because in-situ synthetic method is very complicated, so most dna microarray chip all is to adopt synthetic point sample method.And the preparation of protein chip, because the restriction of method all is the method preparation of adopting synthetic back point sample.
Synthetic point sample method is with after, the quantitative test purified by the synthetic good probe of liquid phase chemical in advance, by the microarray sample application platform, accurately and rapidly with the quantitative point sample of different probe sample on relevant positions such as positively charged nylon membrane or silicon chip, promptly obtain dna microarray or protein chip after the curing.The mode of point sample is divided two kinds, and one is the contact point sample, and promptly spotting needle directly contacts with the solid support surface, and sample is stayed on the solid support; It two is contactless point sample, i.e. specking, and it is with piezoelectric principle or micro-solenoid valve break-make principle sample directly to be sprayed onto the solid support surface by kapillary.The microarray sample application platform of having developed in the market generally all is made up of the three-dimensional mobile device of a cover computer control one cover, a plurality of printing/spray printing pin, a damping base, contain porous plate and a plurality of chip of probe in can putting above the base, a plurality of printings/spray printing pin is connected on the three-dimensional mobile device above base and moves, and probe is taken out directly printing or spray printing on chip from porous plate.This kind equipment has many deficiencies: be limited to the three-dimensional mobile device of a cover, not only point sample speed is slow, and cleaning printing/spray printing pin has taken the plenty of time, inefficiency; Because the plant bottom case size is limited, one time point sample can only prepare the number of chips that can put at most, so a point sample capacity is restricted; With a plurality of printings/same sample of spray printing pin mark, because the individual difference of a plurality of printings/spray printing pin certainly will be brought bigger point sample difference; And same set of printing/spray printing pin gives me a little different samples, and cross-contamination issue is inevitable.Also exist just because of these problems, the preparation equipment of biochip only has the scientific research type at present, does not have quick plant-size equipment.
And the said equipment mostly is import equipment, costs an arm and a leg, and the consumables cost height is not suitable for promoting at home.This kind equipment all is to be designed to probe points on rigid carriers such as slide at present, seldom a bit on flexible carriers such as film.
