Figure 2. Functionalization of amph-NPs with whole antibodies or nanobodies.
(a) Schematic of 3-step process for functionalization of amph-NPs with whole antibodies or VHH nanobodies. (b) SDS-PAGE analysis of anti-CD8 IgG antibody-conjugated amph-NPs (lane 1) and unmodified amph-NPs incubated with antibodies (lane 2). Particles were treated with β-mercaptoethanol to release ligand from the particles prior to PAGE. (c) Quantitative analysis of antibody coupling from SDS-PAGE. (d) SDS-PAGE analysis of anti-CD8 VHH-conjugated amph-NPs (lane 1), unmodified amph-NPs incubated with VHH (lane 2), and unmodified amph-NPs alone (lane 3). Particles were treated with β-mercaptoethanol to release ligand from the particles prior to PAGE.
