摘要:
Anti-CD4 antibody homologs, DNA sequences and recombinant DNA molecules encoding them, prophylactic, immunotherapeutic and diagnostic compositions comprising those antibody homologs, and methods for preventing or treating diseases in mammals, including humans, caused by infective agents whose primary targets are CD4.sup.+ lymphocytes. Such diseases include acquired immune deficiency syndrome ("AIDS"), AIDS related complex, and human immunodeficiency virus infection.
摘要:
Modified human tissue plasminogen activators, the DNA sequences coding on expression for them and methods of making them in hosts transformed with those DNA sequences. The single chain form of these modified human t-PAs, t-PA (Lys 277.fwdarw.X), has a longer half life than the single chain form of native, or recombinant, t-PA, yet, in the two chain form these modified t-PAs have substantially the same affinity for fibrin and substantially the same activity as the two chain form of native, or recombinant, t-PA.
