iso propanol 中文意思是什麼
-
A sds - iso - propanol method suitable for tea plant, which was plentiful of tea polyphenols, had been developed using a modification of chen darning ' s method from different sample storage conditions such as fresh, dry and frozen shoots. it was a quick, easy, economical and effective method. the tactics were as follows : before the cell nuclear membranes were decomposed, the tea polyphenols and proteins etc. were removed
該法提取緩沖液使細胞維持一定的滲透壓，研磨時使細胞核基本保持完整；在細胞核被裂解之前去除細胞質中的茶多酚、大部分蛋白質和rna ；而後用sds裂解細胞核，異丙醇或乙醇沉澱dna ，這樣能經濟、快速和有效地從富含茶多酚、茶多糖等次生物質的茶樹新梢中提取基因組dna 。 -
Then the nucleuses were splitted by sds, dna was precipitated by iso - propanol or alcohol. the average dna yields were 527 u g / g with fresh base
基因組dna平均得率為527 g g鮮重，經鑒定適合進行限制性酶切和rapd擴增。 -
The further study of the six - member ring mechanism with the participation of iso - propanol demonstrates that the calculated ratio of enantiomers agrees with the experimental results essentially
而對質子性溶劑異丙醇參與的六元環機理的研究發現反應產物的對映體組成的計算結果與文獻實驗值吻合較好。 -
Abstract : benzotriazole is a good corrosion preventive compound that can reacts with aldehyde and alcohol. the addition reaction is used to synthesize eight alkoxyalkyl benzotriazoles by benzotriazole, propionaldehyde and methanol, ethanol, propanol, iso - propyl alcohol, n - but anol, iso - butanol, sec - butanol, tert - butanol. their structures were confirmed by elemental analysis, ir and 1hnmr. the mechanism of addition reaction was discussed
