| 中文摘要 | 本研究之主要目的乃探討應用SRY/ZFX及BE5引子進行聚合酶連鎖反應(polymerase chain reaction, PCR)性別鑑定時,細胞數、PCR之前蛋白酶K(proteinase K)處理與否,以及聚合酶種類對於性別鑑定敏感性與特異性之影響,藉以提昇性別鑑定之準確性。試驗分別利用經過純化不同性別乳牛基因組DNA及體外培養之乳牛體細胞(卵丘細胞)做為性別鑑定之材料。結果顯示,經過純化之不同性別乳牛基因組DNA樣品,SRY/ZFX及BE5二組引子之性別鑑定敏感性可達到5 ng,且不論一般Taq聚合酶或於溫條件始啟動聚合作用的Hot Start聚合酶均可獲得專一性的PCR產物;而利用體外培養的乳牛體細胞進行分析時,細胞樣品至少需10個以上,並於PR前先經蛋白酶K前處理,配合使用一般Taq或Hot Start DNA聚合酶進行PCR,是適合的細胞樣品性別鑑定條件。 |
| 英文摘要 | The purpose of this study was to determine the effects of cell numbers, proteinase K treatment prior to polymerase chain reaction (PCR0, and polymerase on the sensitivity and specificity of sex determination by using SRY/ZFX or BE5 as primer. Purified genomic DNA from male and female dairy cattle and in-vitro-cultured cumulus cells were used for the sex determination. The results showed that the sensitivity of sex determination of genomic DNA was 5 ng when Taq or Hot Start polymerase was used in amplification with either SRY/ZFX or BES primers. When the somatic cells were used as samples for determination, treatment with proteinase K and then PCR running with Hot Start DNA polymerase, sexing efficiency would be effectively improved. Ten cells were the minimal numbers required for the successful sexing. |
