We analyzed the polymorphism of MHC class II B gene in 14 Chinese alligators sampled from three different areas: the wild population of Xuancheng in Anhui, the captive population of Changxing in Zhejiang and the captive population of Anhui Research Center for Chinese Alligator Reproduction. The gene fragment was amplified using a pair of specific primers designed from the MHC gene sequence of the Spectacled caiman. A total of thirty-four different sequence (15, 10 and 9, respectively) were detected in sampled Chinese alligators.

为了研究扬子鳄种群MHC基因的多态性，我们选取了安徽宣城野生扬子鳄种群、安徽省扬子鳄繁殖研究中心饲养种群和浙江长兴饲养种群三个亚种群的14条扬子鳄，利用一对特异性引物扩增出扬子鳄MHC II类B基因第三外显子的部分片段，并对其进行了克隆、测序，结果从这些扬子鳄样本中共获得34种不同序列，每个亚种群内分别检测到15，9和10个不同序列。

This study aims at tick vitellogenesis and its mechanism. Six hybridoma cell lines secreting monoclonal antibody against vitellin of the hard tick Haemaphysalis longicornis were produced by fusing myeloma cells (SP2/0) with spleen cells, both from BALB/c mouse which were immunized with the Vn. They were named as 1B5, 2A7, 2B8, 2F2, 3A1 and 3G1, respectively. Further identification indicated that 1B5, 2B8 and 2F2 were of the isotype IgGA, 2A7 was of the isotype IgG1, while 3A1 and 3G1 were of the isotype IgG2a.

为研究蜱类的卵黄发生及其机理，用长角血蜱Haemaphysalis longicornis卵黄蛋白(vitellin，Vn)免疫BALB/c小鼠，取免疫鼠脾细胞与骨髓瘤细胞SP2/0进行融合，经3次克隆化筛选，获得6株能稳定分泌抗Vn的单克隆抗体，即1B5，2A7，2B8，2F2，3A1和3G1.1B5，2B8和2F2亚型为IgGA；2A7亚型为IgG1；3A1和3G1亚型为IgG2a.6株McAb均具有高度特异性，效价在1：105以上。
