抗抗体

In this study, the variable region genes of three stem McAb 1A〓-D〓, 2F〓-B〓 and 2E〓-E〓 against metal-bound tetrapeptide were joined into a single chain antibody with a linker respectively. And insert 39bp fragment of N-terminal CGRP to C-terminal of heavy chain and constitute V〓linker-V〓-CGRP single chain genes.

为获得有催化活性的抗体酶，本文将〓和〓〓三株金属螯合四肽单抗的轻、重链可变区基因，通过linker分别连接成单链基因，并在其后插入编码CGRP的N端十三肽的39bp基因片段，组成〓-linke-〓-CGRP，将该基因克隆入分泌表达载体pTC01中，获得表达产物。

Here we report that there is a dramatic decrease in the ability of a broadly neutralizing antibody to protect macaques against SHIV challenge when Fc receptor and complement-binding activities are engineered out of the antibody.

但一项新的研究表明，抗HIV抗体在以两种方式发挥作用时最有效：一种是通过中和，即直接杀死病毒，阻止其进入T-细胞；另一种是通过杀死感染的细胞。

METHODS: The drug-using characteristics were investigated through a questionnaire and the surface antigen of HBV and antibody against HCVin serum were checked with ELISA.
