基因芯片是指应用原位合成或微量点样等方法 ,将大量cDNA片段、肽核苷酸或寡核苷酸探针有序地固化于支持物 (如玻璃片、硅片、聚丙烯酰胺凝胶、尼龙膜等 )的表面 ,组成密集二维分子排列 ,然后与已标记的待测生物样品中靶分子杂交 ,通过激光共聚焦扫描或电荷偶联摄影像机等特定
Gene chip refers to the application of in situ synthesis or micro-spotting and other methods, a large number of cDNA fragments, peptide nucleotides or oligonucleotide probes in an orderly curing support (such as glass, silicon, polyacrylamide coagulation Glue, nylon membrane, etc.), the composition of dense two-dimensional molecular arrangement, and then labeled with the biological sample to be tested target hybridization, by confocal laser scanning or CCD camera and other specific
