Description
A kind of PCR chip testing instrument with micro probe array of the present invention relates to new departure that manufactures and designs of a kind of PCR-of being used for chip testing instrument with micro probe array device, especially utilize optical CCD device, optical fiber detector, pcr chip attemperating unit, detect gearing, locating device, finish the test of PCR microarray probe circulating detection type biological chip polycomponent automatically.
Round pcr mainly is as a kind of selectivity outer-gene amplification method and since through 25～35 take turns the circulation after just can make DNA cloning 10
6Doubly, in scientific research and medical test, be widely used for many years.But, forbidden being used for clinical diagnosis by health ministry from June, 98 because there are defectives such as false positive in PCR.Its main cause is: the mistake that the labile factor that many experiment conditions in the PCR process (primer design and selection, material mixture ratio, reaction time, temperature, cycle period) etc. cause causes producing PCR is drawn and is increased.It two is that the follow-up electrophoretic detection of PCR process can be judged the fragment that whether obtains length-specific, and can't determine its concrete sequence.Its three, PCR reaction is two discrete processes with detecting, complex operation and increased the chance of polluting.Therefore, for testing conditions and equipment limited in, infirmary, the accuracy of the detection of PCR has been subjected to very big influence.In addition, current PC R amplification procedure has very high requirement for technical level of operators and quality.
Biochip mainly is meant by plane Micrometer-Nanometer Processing Technology and supermolecule self-assembling technique, in microanalysis unit and the system that the solid chip surface makes up.Biochip can integrate many difference in functionality devices, for example, the pre-service of biological sample, the extraction of inhereditary material, the amplification of specific gene fragment, biological probe array and Capillary Electrophoresis form whole microfluid system, with realize to compound, protein, nucleic acid, cell and other biological components accurately, fast, the screening or the detection of large information capacity.Genetic chip is a most important class biochip, and it the is integrated gene probe of dense arrangement in a large number can be analyzed a large amount of genes at short notice, makes people can promptly read and analyze the program of life.
Biochip has extremely important meaning on biological detection, medical test, drug screening and gene sequencing.For example in biology, along with molecular biological continuous development, since the Human Genome Project particularly highly visible was implemented, the data of related nucleic acid, protein sequence and structure were exponential increase.And the most challenging work of next century is exactly after the Human Genome Project is finished, and promptly at the back era gene, how we use a large amount of biomolecule information services in human society, and makes medical science, treatment produce basic revolution.In medical science, " the subordinate phase medical science on system, organ, tissue, the cell level " transforms to " on the gene level; DNA → RNA → protein → protein and nucleic acid interaction, and the phase III medical science on they and the environmental interaction level ".This gene diagnosis of carrying out on molecular level and gene therapy will be familiar with the root that disease produces at all, and will be hopeful basic understanding and treat the major disease that comprises cancer.The fundamental change of these biology, medical science, a mensuration and the analysis that basic prerequisite is a gene order.Can carry out gene sequencing and analysis effectively apace, will have influence on the enforcement of the Human Genome Project, thereby influence further developing of biology, medical science.The method that adopted of tradition gene sequencing comprises a series of numerous and diverse steps such as chemical reaction, gel electrophoresis, and these method spended times are longer, and operates complicated, especially time-consuming and be not suitable for portability and check order fast aspect large scale sequencing.Traditional gene order surveying method is being carried out in the improved process, is that the biochip technology of representative arises at the historic moment with the genetic chip.Biochip technology is with many discontinuous analytic process related in the life science, and as specimen preparation, chemical reaction and analyzing and testing etc. are by adopting microelectronics, technologies such as micromechanics are integrated in the chip, make it serialization, integrated, microminiaturization and robotization.The strong means that provide are obtained and analyzed to the maturation of this technology and use and will bring a revolution in medical diagnosis on disease and the life science association areas such as treatment, new drug development, judicial expertise, food and environment of next century for biological information.
Biochip (genetic chip) is an international research focus in recent years always, and advances just with surprising rapidity.There have been many companies to enter the biochip field in the world, worked out PCR and the integrated biochip of DNA array.These systems prepare a PCR micro reaction pool usually on chip, by controlling the temperature cycles of little reaction, carry out gene magnification, in the gene introduced cross pond after then will increasing, with the hybridization of solid phase micro probe array, detect.Microfluidic channel is further made by Affymetrix company then PCR micro reaction pool.Although the existing report that the round pcr chip detection is integrated is characterized in that whole PCR process carries out in a micro reaction pool.Thereby need to be heated up repeatedly, lower the temperature in the same position of device, this can't be incorporated into the action attitude to PCR and follow the tracks of and quantitative test.And the need certain hour that heats up at present, lowers the temperature, prolonged the working time.
