Antibodies binding to phosphorylcholine (pc) and/or pc conjugates

An antibody or antibody fragment capable of binding to phosphorylcholine and/or a phosphorylcholine conjugate,

• wherein the antibody or antibody fragment comprises a variable heavy chain (VH) domain and/or a variable light chain (VL) domain, and wherein—
• (a) the VH domain comprises an amino acid sequence that includes one, two or three complementarity determining regions (CDRs) selected from the group consisting of
• a CDR1 sequence comprising an amino acid sequence having at least 20%, 40%, 60%, 80% or 100% sequence identity to the sequence of SEQ ID NO:
• 7;
• a CDR2 sequence comprising an amino acid sequence having at least 5%, 11%, 17%, 23%, 29%, 35%, 41%, 47%, 52%, 58%, 64%, 70%, 76%, 82%, 88%, 94%, or 100% sequence identity to the sequence of SEQ ID NO:
• 8;
• and
• a CDR3 sequence comprising an amino acid sequence having at least 11%, 22%, 33%, 44%, 55%, 66%, 77%, 88% or 100% sequence identity to the sequence of SEQ ID NO:
• 9 or 10;
• and/or
• (b) the VL domain comprises an amino acid sequence that includes one, two or three complementarity determining regions (CDRs) selected from the group consisting of:
• a CDR4 sequence comprising an amino acid sequence having at least 7.5%, 15%, 23%, 30%, 38%, 46%, 53%, 61%, 69%, 76% 84%, 92% or 100% sequence identity to the sequence of SEQ ID NO:
• 11;
• a CDR5 sequence comprising an amino acid sequence having at least 14%, 28%, 42%, 57%, 71%, 85% or 100% sequence identity to the sequence of SEQ ID NO:
• 12;
• a CDR6 sequence comprising an amino acid sequence having at least 9%, 18%, 27%, 36%, 45%, 54%, 63%, 72%, 81%, 90% or 100% sequence identity to the sequence of SEQ ID NO:
• 13.
