Targeting Peptide ServicesTailored Peptide Development

Targeting Peptides are a class of functional short peptides capable of specifically recognizing and binding to certain cells, receptors, or tissues. They are widely used in targeted drug delivery, imaging probe construction, blood-brain barrier (BBB) transport, as well as disease-related research such as tumors and inflammation.

Creative Peptides leverages advanced peptide synthesis platforms and molecular modification technologies to provide one-stop targeting peptide services, covering sequence design, custom synthesis, functional modification, carrier conjugation, and targeting validation. We help clients rapidly advance various projects from basic research to preclinical development. We support custom synthesis of classic targeting peptides such as RGD, NGR, T7, Angiopep, and can also design target-specific peptides and construct peptide libraries according to client needs. These peptides are widely applied in anti-tumor, BBB crossing, inflammation localization, targeted imaging, and other research areas. Our services support gram-scale synthesis, high-purity purification, and strict quality control, suitable for small-scale to scale-up R&D phases.
