analysis of catechins in tea 1.since catechin is beneficial to our body, we should know how much catechin is contained in tea. 2. sampling sample preparation analysis through HPLC 3. yes 因为各种tea其catechin 不一定相同 4. 先配制standard concentration之catechin 打HPLC 5.可加一些standard catechin to sample 看其peak会较大则确定是同一compound而beer law 则确定HPLC-UV ok 六 1. isoelectric focusing 之电泳 2. 2D电泳+ms or MALDI 3.no 因apotransferrin +Fe3+ ->transferrin 则两蛋白质电荷不同 4. beer's law and UV absorption 5.since protein structure determine the activity of the protein, and the pH value and ionic strength influence the structure a lot since H bond and salt bridge 6.有人会吗?看底下吧 以上是神的答案 非我的 有要补充底下推文 http://homepage.ntu.edu.tw/~b97203005/analysis.doc http://0rz.tw/4gMBd http://0rz.tw/ ※ 编辑: jasonfghx 来自: 140.112.7.59 (12/17 22:23) 有关TBE http://en.wikipedia.org/wiki/TBE_buffer ※ 编辑: jasonfghx 来自: 140.112.7.59 (12/19 22:50)
