What are the Common Ligands Used in Active Targeting?
Various ligands can be used for active targeting, including:
1. Antibodies: High specificity and affinity for target antigens. 2. Peptides: Smaller in size, easier to synthesize, and can penetrate tissues better. 3. Aptamers: Oligonucleotides or peptides that bind to a specific target molecule. 4. Small Molecules: Such as folic acid, which targets folate receptors overexpressed in certain cancers.
