Studies of the binding of metal to calmodulin and the subsequent binding of metal-calmodulin complexes to the target protein/peptide revealed that the La-content calmodulin complexes to its target exhibit similar affinity with the Ca-calmodulin complexes.However, there were substle differences in protein conformation as well as the kinetical properties between the two kinds of metal-calmodulin complexes, suggesting Ln could produce cellular effects via the Ca/calmodulin signaling systems.

稀土离子和钙调蛋白的结合以及后续和靶酶的结合，在热力学上与钙离子激活蛋白具有相同的亲合力，但在动力学性质上以及细微构象上明显不同，显示稀土离子可通过细胞钙相关信号系统产生特别的生物效应。

The application of such solvent effects to the kinetically controlled peptide synthesis, however, has only recently been exploited.

试验结果表明，在所研究的几种单相共溶剂体系中，木瓜蛋白酶的酰胺酶活性都得到了不同程度的抑制，有些情况下甚至完全被抑制，而酯酶活性则保留了单水相中的全部或部分。

Freezing reaction mixtures as a new approach for kinetically controlled peptide synthesis, however, was developed by Jakubke et al.

但低温酶促肽键合成作为一种新的肽键生成方法则在1990年Jakubke等人的报道之后才开始受到关注。

It was showed that throughout the nuclear division, nuclear membrane did not disintegrate,lamina always existed; But only one lamin peptide (similar to lamin B in higher eukaryotes) was expressed during division,ant its expression quantity changed according to the progress of division: in interphase, lamin was constant; when entering G1 phase, lamin increased sharply; then, increased slowly untill division finished.

结果表明：在整个核分裂过程中，核膜不崩解，核纤层结构一直存在；但随着分裂的进展，始终只有一种成分（类似于高等生物lamin B ）的表达；其表达量随着分裂时相的推移而变化：间期时，比较恒定，进入G1期时明显增加；以后不断略有增加，直到分裂完成。

Globin chain analysis proved the α chain to be abnormal The fingerprint of the abnormal α chain and the amino acid sequence of the abnormal peptide obtained indicated that the α 34 leucyl residue had been replaced by arginyl...

将异常α链经柱层析分离纯化后作指纹图，把指纹图的异常肽斑洗脱，用微量双偶合法作氨基酸顺序测定，发现异常肽斑为α34亮氨酸被精氨酸取代，由此证实此异常血红蛋白为Hb Queensα_2~(34Leu→Argβ_2。

Considering, it is limited the cross-reactivity displayed by a single HVR peptide. We designed to ligate several high reactive HVR1 genes, and the recombinant fused protein containing several HVRls would have the ability to cross-react with most of HCV infected sera, and could be an effective immunogen of HCV vaccine.

但我们认为通过一条肽获得的交叉反应毕竟是有限的，故设想如果能将几个具有高交叉免疫反应性的HVR1片断用基因重组的方法连接起来，可能会获得与绝大多数病人血清发生免疫交叉反应性的抗原，并为疫苗的研究提供真正有效的免疫原。

The obtained peptide can eliminate free radicals, inhibit linolic acid peroxidation activity and chelate metallic ions, thereby having the advantages in terms of nutrition and healthcare.
