1、primer6.O引物设计程首先,须要知道基因序列，如，我们要设计rat的CK18mRNA检测的引物，我们先到这个网站查找CK18mRNA的基因序列，ZncbiNiimiC4M*rcgr*54StrctGmA6FmGewct&MdcmGn7XlJj*NCBI!“foBMMtf09yhto*Mt%*sy*.MdhM*ro*R*9ccm*Iobcm-：IMc1110yasIRmwt12K三OVUOMMPMCPopSetProoeProtenProtonCU5*sPuQecnPuOCnemCOnPoUrKJPbCnttnrf力/datMmgNCerIGftNC8dMerMtwwe153W011*WW

10、”|0,51|也匍鼻=Wl-SeuehceInformaflonSearchStatus点击这个图标出现卜面对话框，这里可以选择引物在序列哪些地方设计引物，我一般不更改，也就是引物可以设计在整个序列，你也可查一下序列才几个区，一般引物应当跨两个区。之后点击primerParameters这里可以设置退火温度、引物K度、产物K度等，我一般只是更改产物K度，我一般设为100到300bp,因为假如产物太大，在染料法中会影响扩增效率,之后点击Search之后出现下面对话框SearchCompletedSequencesProcessed:1EIapsedTime00:00:00点击OK出现下面引物序列

11、这个时候引物设计完成，我们须要对引物进行验证，我一般到NCBI()上验证，进去后点击最下面菜单中的B1.AST之三三AA一一三三ht1-E三三三三.三点击这个图标BasicB1.ASTChooseaB1.ASTprogramtorunnuclsoUdsbldstProtioblastblast-SearchanucleotidedatabaseusinganucleotidequeryAlgonthmsblastn,megablast,discontiguousmegaWastSearchproteindatabaseusingaproteinqueryAlgonthms.blastp,ps-blast,ph-Wast.delta-blastSearchproteindatabaseusingatranslatednucleo
