After the contrast experiment, it uses 732 cation resin to depurate the GSH solution, theconcentration of the eluant is the 0.2mol/L NaOH solution, the GSH maximum returns-ratio is 68.37％.

经过对比试验，本研究采用732阳离子交换树脂进行谷胱甘肽粗提液的纯化，经试验洗脱液选择浓度为0.2mol／L的NaOH溶液，谷胱甘肽最大回收率为68.37％。

The variation of plasma vasoactive peptide concentration was not only related to UAP attack but also significant to the maintance coronary diastole and corculation.

UAP的发生与血管活性肽的变化密切相关，血管活性肽对维持冠脉舒张和循环有重要意义。

And 3.3%; The digestibility of CF had been improved 14.5%, 6.2% and 9.8%.

饲喂小肽组和灌注小肽组差异不显著(P＞0.05)。

Since a dipeptide is formed, translation initiation is not affected, nor is the first step of elongation―the binding of a charged tRNA in the A site and the formation of a peptide bond.

既然能够形成二肽，说明翻译的起始不会受到影响，同时，延伸的第一步即荷载的tRNA进入A位点并形成肽键也不会受到影响。

The rest of desired dipeptide aldehydes were prepared by oxidation of their dipeptide alcohols.

然后在Parikh-Doering条件下氧化二肽醇，所得产物通过LC/MS制备分离得到二肽醛。

Analysis of the incubation fluid showed that 2.4 to 6.4mmol dipeptide disappearedfrom the incubation fluid of per gram of intestine in the first 15 minutes of incubation.

旨在测定：同一浓度下的二肽不同肠段的肠囊各部位的水解差异，及不同的浓度的二肽在同一肠段的不同肠囊部位上的水解差异。

This indicates that the peptide bond has some characteristics of a double bond, because of resonance stabilization with the carbony1 oxygen.

肽 当一个氨基酸分子的氨基与另一个氨基酸分子的羧基起反应时，便形成一个肽键，同时释放出一分子水。

At the beginning, HLA class I/peptide complex teramer was prepared, including the most frequent alleles in Chinese, i.e., HLA-A2 and HLA-A24. Then the aAPCs were assembled by coating a cell-sized bead with pMHC and anti-CD28 antibody, which were able to provide the dual signals required for T cell activation, and used as stimulator to generate pMHC-specific CTL by co-culture with allogeneic peripheral blood lymphocyte.

首先制备包括我国人群基因频率最高的HLA-A2，HLA-A24的HLA/抗原肽四聚体，在此基础上，制备能够为T细胞提供第一、第二活化信号的aAPC，其表面包被的HLA/抗原肽复合物容易控制，用于诱导同种个体的T细胞产生同种CTL。

We purified the target protein under natural conditions by MCAC through Ni-NTA resin. The purity of this fusion PH domain of IRS-1 was up to 98％. We paned out the oligopeptides that can bind to this target protein from a phage displayed random duodecimal peptide library. The identities of peptide sequences of positive clones were analyzed.

因此，我们利用融合表达载体pRSET在T7启动子的调控下表达出氨基端带六个连续组氨酸标签的IRS-1的PH结构域，利用Ni-NTA介质在非变性条件下对目的蛋白进行了金属螯合亲和层析纯化，获得了纯度达98％以上的PH结构域融和蛋白，以此为靶分子，从噬菌体展示随机12肽库中筛选出能够与其相结合的短肽，并分析了阳性克隆的序列一致性。

In this paper, we determined the toxicity of transgenic Betula platyphylla with Bt spider peptide gene. Larvae of Lymantria dispar were feed on leaves of transgenic Betula platyphylla with Bt spider peptide gene, The mortality, reduced ratio of weight, ecdysis index and schedule time of every instar.

本文对转Bt C肽蜘蛛杀虫肽的白桦进行杀虫性测定，对取食对照和转基因植株舞毒蛾幼虫的死亡率、体重降低率、蜕皮指数、幼虫各龄级历期等指标进行了分析，证明外源基因已经成功插入白桦基因组中，并且能够表达杀虫蛋白。
