Recombinant DNA coding for a T-cell receptor chain, process for preparation and antibodies and pharmaceutical compositions comprising the same

摘要

Recombinant DNA containing a chimeric nucleotide sequence encoding a T cell antigen receptor chain, the said sequence consisting of: - a sequence of mammalian origin encoding the entire variable (V), diversity (D) and junction (J) regions, - and a sequence of murine origin encoding the constant complementary region (C) which is absent from the above mammalian sequence, the two sequences being joined at a natural or artificially created restriction site, antibodies obtained using the said DNAs, pharmaceutical composition and diagnostic products containing them and a process for preparing them.
