Anticoagulant
Anticoagulant — A substance that prevents blood clotting, such as EDTA or heparin, used in sample collection tubes for peptide hormone blood-level measurements.
What Is an Anticoagulant?
An anticoagulant prevents blood clotting by inhibiting coagulation cascade proteases. Several natural and synthetic peptides function as anticoagulants: hirudin (65 residue leech peptide, direct thrombin inhibitor) is the most potent natural anticoagulant known. Anticoagulant peptides also appear in laboratory contexts, where blood collection tubes for peptide biomarker analysis require specific anticoagulant choices.
Peptide Anticoagulants
- Hirudin: 65 AA peptide from leeches. Inhibits thrombin with femtomolar Kd
- Bivalirudin: Synthetic 20 AA hirudin analog. FDA-approved for PCI procedures
- Lab use: EDTA or heparin tubes for blood collection. Choice affects peptide ELISA results
