We found that sit variant gene ( slt2vha ) was identified in strains e. coli o157 : h7 isolated from patients and dung beetles 2000 in xuzhou city, jiangsu province. the primers used for stx2 variant analysis are shown in tablel. genomic dna restriction fragments digested by pstiwere sonthern - blotted and hybridized with an stx2 - specific dna probe. the probe was prepared fromed a 285 - bp pcr productof the strain 882364 stx2 gene obtained by using the specific primer pair ( tablel )
2000年在江蘇省徐州市銅山縣腹瀉病患者的糞便標本分離的10株產生志賀毒素的菌株以及從蜣螂腸道分離到的4株產生志賀毒素的大腸桿菌o157 ： h7 ，屬于另兩個pfge型，和1986 、 1987 、 1988年在徐州市腹瀉病患者的糞便標本分離的菌株pfge圖譜不同。 -
Part 1 : identification of a novel gene, tsarg2, and its sequence character cloning new apoptosis - related novel gene is a key to further understanding of apoptosis mechanism and the biological process of germ cell, and it is of momentous significance on clarifying physiology and pathology process of spermatogenesis. to rapidly attain human novel gene full - length cdna sequence, the gene - specific primers and the vector - specific primers have been designed for successful performing nested pcr and draft human genome searching to rapidly identify the tsarg2 ( genebank accession number ay040204 ) 5 " end from a human testis cdna library by using a cdna fragment ( genebank accession number be644542 ) as a electronic probe, which was significantly changed in cryptorchidism and represents a novel gene. furthermore, a mouse homologue of this gene was identified ( genebank accession number af395083 ) by lab on - line
本研究分為三個部分，其主要實驗方法及實驗結果如下：第一章tsarg2基因的克隆與序列分析從已獲得的在隱睪和正常睪丸對照中表達量有明顯差異的est片段（ be644542 ）入手，設計了基因特異性引物和載體特異性引物進行巢式pcr擴增，結合人類基因組草圖搜索法，從睪丸cdna文庫中快速分離出人類睪丸凋亡相關基因的5末端而獲得全長cdna ， genbank登錄號為ay040204 ，同時應用生物信息學的方法克隆了該基因在小鼠中的同源基因， genbank登錄號為af395083 。 -
To avoid cross hybridzation due to the conservative myb - domain a fragment specific only for the c - terminal part of the gene was used as a probe. independent of the restrictase used for digestion single band was detected
實驗中為了避免由於保守的myb結構域而造成該基因和同類轉錄因於的雜交，所用探針僅用mxmybl基因c一端的特異性片段。
