生物活性评价 Data for two antibody clones measured by competition ELISAs are provided in US 6682736 . Clones 4.1.1. and 11.2.1 inhibit binding of CD80 and CD86 to CTLA4 with almost identical IC50 values. The affinity for direct binding between antibody and CTLA4 is only provided for subclone 4.1.1.1 in this patent.
评价 Tremelimumab is a fully human investigational monoclonal antibody targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA4, CD152). Tremelimumab was designed as an antineoplastic agent. A BLAST sequence alignment matches tremelimumab to patent US 6682736, and identifies antibody clone 11.2.1 .
