Application
May be used for the removal of DNA from protein samples or for the purification of DNA binding proteins. It may be used as an alternative to polybrene in retroviral-mediated gene transfer.
Biochem/physiol Actions
Protamine in the form of solid lipid nanoparticles (SLN) promoted transfection with plasmid DNA more efficiently and with less cytotoxicity than comparable SLNs composed of Esterquat-1.
Protamine sulfate is a small cationic protein that binds and precipitates DNA. Neutralizes the anticoagulant activity of heparin. Inhibits lipoprotein lipase.

Galactosyltransferase was purified from Golgi membranes of lactating-rat mammary gland and studied with respect to its physical and enzymic (lactose synthetase) properties. The enzyme occurred in both monomeric (43-46 kDa) and apparently dimeric (90 kDa) forms. It was very unstable

The antimicrobial effect of protamine (clupeine) on a range of gram-positive and gram-negative foodborne pathogens and spoilage bacteria, was evaluated using an agar dilution assay and a broth dilution assay with Alamar Blue as growth indicator. Protamine was tested alone
