Application

Ac-Hirudin Fragment 55-65 non-sulfated is a C-terminal fragment (fibrinogen-recognition site binding) of the leech anticoagulant peptide hirudin. Ac-Hirudin Fragment 55-65 may be used with other C-terminal fragments to study optimal N-terminal and position 56 functionalities for C-terminal fragment analogues of hirudin.

During sepsis, lipopolysaccharide (LPS) triggers the development of disseminated intravascular coagulation (DIC) via the tissue factor-dependent pathway of coagulation resulting in massive thrombin generation and fibrin polymerization. Recently, animal studies demonstrated that hirudin reduced fibrin deposition in liver and kidney

Like most metalloproteases, matrix metalloprotease 2 (MMP-2) is synthesized as a zymogen. MMP-2 propeptide plays a role in inhibition of catalytic activity through a cysteine-zinc ion pairing, disruption of which results in full enzyme activation. A variety of proteases have
