## FAQ

### What is the main advantage of the ADP1 peptide over its parent peptide Z34C?

ADP1 has markedly enhanced chemical and proteolytic stability. It is more resistant to breakdown by enzymes and chemical degradation, making it a more durable tool for experiments.

### How does ADP1 assemble antibodies?

ADP1 forms a stable dimer (a pair of peptides). This dimer bridges the Fc regions of two neighboring antibodies. Additional ADP1 molecules can bind and bridge further, creating higher-order, spiral assemblies of antibodies.

### Can ADP1 be used with standard off-the-shelf antibodies?

Yes. The study demonstrates that ADP1 promotes higher-order association of full-length IgG antibodies without requiring any genetic modification to the antibody scaffold itself.
