Is protamine an anticoagulant?
Protamine, an arginine-rich basic cationic protein derived from salmon sperm, has high affinity for negatively charged sulfated glycosaminoglycans, including heparin. Paradoxically, since 1937, protamine has been reported to have anticoagulant activity.
What is protamine reaction?
May 19, 2013. “It binds to heparin to form a stable ion pair which does not have anticoagulant activity; on its own, protamine has a weak anticoagulant effect.” Protamine sulfate is a drug that reverses the anticoagulant effects of heparin by binding to it.

Is protamine a protein?
Protamines are small, arginine-rich, nuclear proteins that replace histones late in the haploid phase of spermatogenesis and are believed essential for sperm head condensation and DNA stabilization. Protamine and protamine-like (PL) proteins are collectively known as the sperm-specific nuclear basic proteins (SNBPs).
Is protamine zinc insulin?
Protamine zinc insulin (PZI) is a long-acting insulin combination. Protamine zinc is added to insulin as a means of slowing insulin absorption. PZI once was made with beef and pork insulin but the PZI described in this monograph is made with human recombinant insulin.
What is protamine in insulin?
A fish protein, protamine, has been added to the Regular human insulin to delay its absorption. This long acting insulin is a cloudy suspension that needs to be remixed thoroughly before each injection. Because NPH is a suspension of different sized crystals, it has a very unpredictable absorption rate and action.
