Table 2. Summarization of Bioengineered AH Vaults’ Ability to Selectively Associate with a Small Sample Set of Therapeutic Compounds with Different Physicochemical Properties via Noncovalent, Reversible Association within a Novel Internalized Lipophilic Core Microenvironment Generated by the Covalent Attachment of a Unique Amphipathic α-Helix Peptide (NS5A1-31) to the MVP.
