【摘要】:目的探讨荧光半定量逆转录-聚合酶链式反应(fluorescencesemi-quantitativereversetranscrip-tase-polymerasechainreaction,RT-PCR)技术检测大鼠死后不同时间肾3-磷酸甘油醛脱氢酶(GAPDH)mRNA含量变化对死亡时间(postmorteminterval,PMI)推断的应用价值。方法28只大鼠断颈处死后置于20℃温控系统内,利用荧光标记半定量RT-PCR技术检测大鼠肾GAPDHmRNA在死后48h内相对表达量的变化情况。结果在死后即刻至40h内大鼠肾均可检测出GAPDHmRNA,且其扩增产物呈规律性下降。结论荧光半定量RT-PCR技术检测大鼠死后肾GAPDHmRNA含量变化对PMI推断具有一定的应用价值。
[Abstract]:Objective to investigate the value of fluorescence semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) in determining the content of GAPDHN mRNA in the kidney of postmortem intervalPMIs in postmortem intervalPMIs of rats at different postmortem time after death by using fluorescence semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Methods 28 rats were killed by cervical amputation and placed in the temperature control system at 20 鈩,
