  1. Gene chips is high density probe array which is composed of nucleic acid or nucleic acid band arranged on the solid support media according to the definite order. it can detect unknown molecule by nucleic acid hybridize principle

    基因晶元是將核酸或核酸片段按照一定的順序排列在固相支持物上構成高密度探針陣列，利用核酸雜交原理檢測未知分子。
  2. Therefore, the determination of seb is very important for food hygienic analysis as well as for clinical analysis. nucleic acid hybridization technique is one of the widely - used methods in molecular biology and gene technology. the present work has developed piezoelectric biosensors used in the detection of seb dna by tacking the piezoelectric quarts crystal as a sensitive component while synthetic oligonucleotide probe as recognize molecule

    其中b型葡萄球菌腸毒素（ seb ）是一種通常條件下更穩定，毒性最強的毒素，而核酸雜交技術則是分子生物學和基因工程中最常用和最基本的方法之一，因此本論文以該毒素的產毒基因為檢測對象，以壓電石英晶體為敏感元件，以合成的寡核苷酸探針為識別分子，構建了用於seb基因檢測的壓電生物傳感器。
  3. The specificity of the nucleic acid probe was very strict. lt reacted positively with iltv dna only and it react negatively with the nuleic acid of ndv, bv and ibdv. the sensitivity of this kind of probe is very high. ilt could even detect 20pg ' s iltv dna

    結果表明：該種核酸探針具有高度的特異性，它僅與iltv的dna呈現陽性反應，而與新城疫病毒、傳染性法氏囊病病毒和傳染性支氣管炎病毒的核酸等均呈陰性反應。該種探針具有高度的敏感性，能夠檢測到20pg的iltv的dna 。
  4. In the present experiment studies, an acute traumatic model of lateral cortical impact was employed to study expressive changes of microtubule associated protein - 2 ( map - 2 ), cyclooxygenase - 2 ( cox - 2 ), glial cell line - derived neurotrophic factor ( gdnf ), caspase - 3 mrna and protein after brain injury in rats. immunocytochemical staining, western blotting, nucleic acid in situ hybridization with an oligonucleotide probe and computer image analysis were used to detect the dynamic changes of map - 2 mrna, cox - 2 mrna, gdnf mrna, and caspase - 3 mrna in the cortex after moderate traumatic brain injury ( tbi )

    本實驗從自行設計大鼠腦損傷落體打擊器開始，先行建立了一個便於觀察和施加處理因素、控制性好、重復性好的動物模型，選用30g擊錘從25cm高處下落，沖擊應力d為355 . 09kpa ，打擊大鼠右頂部，造成中等程度的閉合性腦損傷，從病理形態學、組織超微結構觀察及微管相關蛋白- 2 （ microtubuleassociatedprotein2 ， map - 2 ） 、環氧合酶- 2 （ cyclooxygenase2 ， cox - 2 ） 、膠質源性神經營養因子（ glialcellline - derivedneutrophicfactor ， gdnf ） 、 caspase - 3基因及蛋白表達的時間性變化，詳盡系統地闡述腦損傷后各指標變化的時間規律性及表達差異可能的形成機制。
