RDM1 antibody

与基因沉默有关的特殊基因RDM1

奥地利格雷戈尔·门德尔植物分子生物学研究所日前宣布，一个包括该研究所、中国同济大学、美国加利福尼亚大学等机构科学家在内的国际科研小组发现了一种特殊基因，没有它，植物细胞内其他一些基因就只能保持沉默。最新一期英国《自然》杂志网络版发表了这个国际科研小组的论文。这一科研小组发现的特殊基因名为RDM1，它可以编码生成一种小蛋白，从而参与指导其他基因的表达。科学家指出，基因一般处于被保护状态中，只有通过所谓的甲基化，即与甲基接触，才能表达并发挥作用。如果去除RDM1，被保护的基因就无法甲基化，也就无法

Generation of Antibody Molecules Through Antibody Engineering

been overcome to a large extent using genetic-engineering techniques to produce chimeric mouse/human and completely human antibodies. Such an approach is particularly suitable because of the domain structure of the antibody molecule ( 2 ), where functional

The Antibody Molecule

The importance of antibody molecules was first recognized in the 1890s, when it was shown that immunity to tetanus and diphtheria was caused by antibodies against the bacterial exotoxins (1 ). Around the same time, it was shown that antisera
