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.
