Methods Purified 5-LO fragment was injected into male pronucli and the firtilized eggs were transplanted into pseudopregnant mice. PCR and Southern blot were used to detect the genotype of DNA separated from the newborn mouse tail tissues. RT-PCR and Western blot analysis were used to detect the gene transcription and expression. Results PCR and Southern blot results showed that 7 of 25 mice were transgenic mice.

通过显微注射的方法，将5-脂氧化酶基因片段(6.8 kb)导入BDF1受精卵雄原核并移植到同期受孕的假孕母鼠输卵管中，对产出仔鼠的鼠尾组织DNA进行PCR、Southern blot检测，对9、20、24号转基因小鼠分别提取腹腔细胞、骨髓细胞及脾、肾组织总RNA和蛋白，并采用RT-PCR、Western blot方法进行转录水平检测和蛋白表达检测。

MATERIALS AND METHODS: Arg to Ser mutation was introduced into the 249 position of the p53 gene by knock-in method. These ES cells with this mutation were selected according to the homologues-recombination with PCR and Southern blot. The positive ES cells without a selection marker were injected into blastocysts recovered from Hprt(superscript -/-) mice, which were derived from Hprt-deficient ES cells. The injected blastocysts then were implanted into pseudopregnant females.

材料与方法：利用基因打靶技术在小鼠胚胎干细胞p53基因249编码子中引入点突变，使编码子249由精氨酸变成丝氨酸，然后将含突变的ES细胞显微注射到Hprt小鼠囊胚中，将注射过的囊胚植入假孕的雌性小鼠子宫，到第14d取小鼠胚胎纤维母细胞，用含HAT的培养液筛选出从ES细胞分化而成的鼠EF细胞，经测序证实细胞含有由249Arg到Ser的突变。

DNA was microinjected into male pronuclei of fertilized mouse eggs,the injected mouse eggs were then transplanted into the oviduct of pseudopregnant female mice.

摘 要：目的建立人纤溶酶原激活物抑制物1(PAI-1)转基因小鼠。方法利用构建的高效真核表达载体pCAGGS-PAI-1，制备注射用DNA。

Six hundred ova were transfered into twenty-nine pseudopregnant recipients. Fifty-five offspring were born from the ova mircroinjected with the Bcl-2 fragment expression cassette.Twelve of them were proved to be gene integration positive by PCR .Four founder mice,two male and two female ,were further confirmed to be transgenic by Southern hybridization.

用BglII+SalI+PvuI三酶切pWBS和用BglII+BamHI双酶切pWCS，分别回收并纯化3.0kb的基因片段WAP-Bcl-2-SV40polyA和3.5kb的基因片段WAP-c-myc-SV40poly，作为目的基因，通过受精卵显微注射技术，分别导入C57BL／6J雌鼠与DBA／2J雄鼠交配的F1代小鼠受精卵的雄原核中，各注射约1000枚，将存活的受精卵各600枚分别移植至29只假孕母鼠输卵管壶腹部内。

In situ hybridization using biotinylated POMC cRNA probe made it possible to localize POMC mRNA in the rat ovary. POMC mRNA predominantly existed in corpora lutea of diesturs, pregnant and pseudopregnant rat ovaries. POMC containing cells scattered in the ovarian intertitium were seen. The amount of POMC mRNA in granulosa cells was negligible.
