Rep. Adam Schiff ( D-Burbank) said the successful test shows the need for the system. 众议员谢安达表示,这次测试的成功显示了建立系统的必要性。
It showed a positive reaction in periodic acid Schiff's glycoprotein staining test. 过碘酸西夫氏糖蛋白染色呈阳性反应。
Chitosan functional polymer containing Schiff base group was synthesized by chemical modification of amino group of chitosan with α ketoglutaric acid ( KCTS). The synthesis conditions were optimized by orthogonal test method. 利用壳聚糖C2位上活泼氨基与α酮戊二酸进行大分子反应,采用正交试验法优化合成条件,合成了带有席夫碱基团的功能高聚物(简称KCTS)。
