指纹鉴定法

By adopting DNA fingerprints analysis and polyacrylamide gel electrophoresis simultaneously,the author made an genetical study on analytical evaluation of kindred relationship and contents of serum protein and esterase of a female hinny and her offspring bred after her mating with a masculine ass.

采用DNA指纹分析和聚丙烯酰胺凝胶电泳法，对一例与公驴交配生育了后代的母|JUE||TI|后代进行了亲缘鉴定和血清蛋白、酯酶遗传的分析。

A quick DNA extraction technique which was fitting for maize variety identification and establishing DNA fingerprinting pool was explored ,and the technique was well applied in the following tissues for DNA extraction : embryo, endosperm; radicel, coleoptile , hypocotyl from germinated 1～3 days material .

本实验探索了适用于玉米品种鉴定及DNA指纹库构建的玉米品种DNA快速煮沸法，用快速煮沸法提取了玉米种子胚、胚乳；水培初生根、侧根；种子出苗后的初生根、侧根、胚芽鞘、胚轴、叶片等组织DNA，结果表明，种子胚、胚乳组织；水培2～4d水培初生根、侧根组织；出苗1～5d的胚芽鞘、胚轴组织用快速煮沸法提取DNA效果较好。

MethodsChromatographic fingerprint of Amomum villosum,Amomum chinense and Alpinia zerumbet was determined by RP-HPLC and the gradient elution mode was applied in chromatographic separation,data were analyzed by Fingerprint Similarity Evalution Software to compare the similarity of samples.

目的建立砂仁及其混淆品的高效液相色谱指纹图谱鉴定方法方法采用RP-HPLC法，梯度洗脱，测定阳春砂、海南假砂仁及艳山姜的指纹图谱，并作相似度比较分析。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
