Serum immunoglobulin of Amur sturgeon Acipenser schrenckii, Chinese sturgeon Acipenser sinesis and Huso sturgeon Huso dauricus which were healthy and unimmuned, was first time respectively purified by using saturation ammonium sulfate precipitation followed by Sephadex G-200 gel column chromatography. Molecular weight and partial characterization of Ig and heavy chain and light chain of Ig were measured by polyacrylamide gel electrophoresis, SDS polyacrylamide gel electrophoresis, Western blotting and Ouchterlony method.

为此，本文着重对茂基或茚基稀土烃硫基、烷氧基配合物的合成、性质及其热稳定性进行了较系统的研究。

The synthesis and characterization of asymmetric dinuclear and mononuclear vanadium complexes show that the pH value is very important for the products\' formation and isolation. In some pH range, theα-alkoxy bridge was easy to break and form asymmetric dinuclear and mononuclear vanadium structure.

三、不对称的双核钒和单核钒配合物的合成和表征显示，pH值对产物的形成和分离具有至关重要的作用。pH值在一定范围内，柠檬酸的烷氧基氧作为桥氧的化学键才容易断开，从而形成不对称的双核钒和单核钒结构。pH值不仅影响不对称双核V_2O_3钒配合物和单核钒配合物的形成，还关系到钒还原的速度。

Transgenic plants expressing GNA showed significant insecticidal activity towards \\omoptera insects such as aphids and brown planthopper in bioassay and feeding tests.In this paper a lectin gene was firstly isolated from leaves of Zephyranthes grandiflora, belonging to Amaryllidaceae, by the use of rapid amplification of cDNA ends technique. Characterization, functional prediction and construction of plant and prokaryotic expression vector of this novel gene were studied.

本实验采用cDNA末端快速扩增(Rapid amplification of eDNA ends，RACE)技术，首次从中国特有的野生植物韭莲(又名风雨花，Zephyranthes grandiflora)的叶片中分离克隆出了一个新的凝集素基因，对基因进行了序列分析和功能预测，并成功地构建了韭莲凝集素基因的植物表达载体和原核表达载体。

Molecular cloning and characterization of the novel lection gene. Primers were designed based on conserved sequences of other lectin genes from Amaryllidaceae. A novel lectin gene was isolated from Zephyrathes grandiflora. The full-length cDNA of Zephyrathes grandiflora lectin was 955bp, containing an open reading frame (576bp) encoding a peptide of 191 amino acids. The gene was named as zga (Zephyrathes grandiflora agglutinin), with its encoding protein showing 59% similarity to GNA.
