多乐彩的玩法:Antibody Humanization Service (NOT available temporarily)

Antibody Humanization Service Features

江西体彩11选5多乐彩走势图今天 www.phcnlx.com.cn The mouse antibody has a strong immune response to humans and can induce a human anti-mouse antibody response (HAMA response), which affects the safety and therapeutic effect of the mouse Mab in clinical application. Mouse antibodies can be genetically modified to obtain a structure similar to that of human antibodies, so as to avoid recognition by the immune system and avoid HAMA. Sino Biological Inc. uses CDR grafting technology and computer-aided structural modeling to humanize mouse Mab and rabbit Mab to ensure humanization >90%. Compared with the original mouse antibody or chimeric antibody, the affinity is substantially unchanged, and techniques such as antibody affinity maturation can be provided to further increase the affinity of the humanized antibody.
