Heparin
Heparin — A highly sulfated glycosaminoglycan used as an anticoagulant and known to interact with numerous growth factors and peptides through electrostatic binding.
What Is Heparin?
Heparin is a highly sulfated glycosaminoglycan that inhibits blood coagulation by activating antithrombin III. In peptide research, heparin-binding peptides are used for growth factor delivery, tissue engineering, and antimicrobial applications. Heparin also interferes with many peptide assays and must be considered in blood collection protocols.
Peptide Connections
- Heparin-binding motifs: XBBXBX and XBBBXXBX patterns (B = basic residue) found in growth factor-binding domains
- AMP interaction: LL-37 binds heparin, modulating its antimicrobial activity
- Sample collection: Heparin tubes preferred for peptide biomarker blood draws (vs. EDTA for some analytes)
