  A large range of functional groups have already been made into FSL Kode constructs. These include:
  * Carbohydrates – ranging from monosaccharides to polysaccharides and including blood group antigens, hyaluronic acid oligomers and sialic acid residues
  * Peptide/protein – ranging from single amino acids to proteins as large as antibodies
  * Labels – including fluorophores, radioisotopes, biotin, etc.
  * Other – chemical moieties such as maleimide, click residues, PEG, charged compounds
  Note 1: Multimeric – the presentation of the F residue can be as multimers with controlled spacing and be variable.
  Note 2: Mass – the mass that can be anchored by an FSL Kode constructs can range from 200 to >1x10 Da
