Essentials Bovine (HBI) and porcine (HPI) heparins differ in structure and anticoagulant activity. Protamine‐neutralization was evaluated on a variety of physical‐chemical methods. HBI requires more protamine than HPI to fully neutralize its anticoagulant activity. Protamine preferentially removes higher‐sulfated chains of HBI while HPI is evenly precipitated.
