The Biomolecule Toolkit supports a diverse set of biological modalities such as peptides, oligonucleotides, proteins, antibodies, antibody drug conjugates, nanoparticle conjugates, including those containing non-natural or chemically modified residues and chemical decorations. Any of the above may be represented with full, partial, or no chemical structure information or added annotations. All other biological assets such as cell lines, plasmids, pooled samples, and clones are represented by their relevant metadata and annotations.
