Protamine sulfate is a small cationic protein that binds and precipitates DNA. It may be used for the removal of DNA from protein samples or the purification of DNA binding proteins. Protamine sulfate may also be used as an alternative to polybrene in retroviralmediated gene transfer.2
Protamine sulfate has antibacterial properties3 and inhibits pepsin activity.4 Protamine sulfate and other polycations have been shown to inhibit the classical pathway of complement.5 It neutralizes the anticoagulant activity of heparin6,7 and inhibits turnover of lipoproteins by lipoprotein lipase.8 The aggregation of erythrocytes in the presence of protamine sulfate, for application to the prediction of MN phenotypes, has been investigated.9
