The USAN Council is involved in coining names for various biological products: insulins, interferons, interleukins, growth hormones, colony-stimulating factors, cytokines, monoclonal antibodies and coagulation factors. With increasing development of highly purified biological extracts and recombinant materials, the council has had a greater role in assigning names and developing nomenclature rules for these agents.

Please use the following MS Word document sequence templates to submit in a table format:

USAN and INN requirements for biological substances include the following:

  • Complete mature amino acid sequence (DOC) in a MS Word document
  • Single-letter codes for each amino acid, displayed in groups of 10 characters with 5 groups per line and a number indicating the position of the last amino acid at the end of each line
  • Positions of all disulfide bridges and post-translational modifications should be listed after the sequence
  • Glycosylation patterns (including site, type of sugar, etc.)
  • For recombinant proteins: Expression system and comparison with native sequence
  • Complete mature amino acid sequence (DOC) in a MS Word document
  • Single-letter codes for each amino acid, displayed in groups of 10 characters with 5 groups per line and a number indicating the position of the last amino acid at the end of each line
  • Glycosylation patterns (including site, type of sugar, etc.)
  • Precursor nucleotide sequence with spaces between codons and translation, with numbered lines
  • CDR-IMGT (DOC)
  • IG class and subclass, IG format
  • Species or taxonomy related structure (chimeric, humanized, etc.)
  • Name and/or structure of targeted antigen
  • List of all disulfide bridges and their locations
  • Expression system
  • Clone name(s) and laboratory code name(s)
  • Name/code designation
  • Characterization/description
  • Cell source
  • List and description of manipulation (culture conditions included)
  • If genetic manipulation: the detailed description of the vector and insert should be provided

Nucleic acids include DNA vaccines, oligonucleotides and gene therapy products.

  • Full nucleotide sequence with pertinent regions (e.g., coding regions, control regions) delineated
  • For gene therapies, schematic map of the product and an annotated sequence that delineates relevant sections
  • Details of pegylation: end group, polymer chain (with average number of repeat units to two significant figures), details of the linker, point of attachment of the linker to the active moiety
