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.
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 salt from salmon has been used:
- in the pretreament of cells to study its effect on respiratory syncytial virus infection
- in lentivirus production
- to derivatize it into a diazeniumdiolate NO donor
Biochem/physiol Actions
Protamine sulfate is a small cationic protein that binds and precipitates DNA. Neutralizes the anticoagulant activity of heparin. Inhibits lipoprotein lipase.
General description
Protamine are proteins rich in cysteine and arginine. It possesses many phosphorylation sites. It is found to be localized to the sperm head.

β-Thalassemia is one of the most prevalent genetic diseases worldwide. The current treatment for β-thalassemia is allogeneic hematopoietic stem cell transplantation, which is limited due to lack of matched donors. Gene therapy has been developed as an alternative therapeutic option

Here we describe lentivirus-infected cell microarrays for the high-throughput screening of gene function in mammalian cells. To create these arrays, we cultured mammalian cells on glass slides 'printed' with lentiviruses pseudotyped as vesicular stomatitis virus glycoprotein, which encode short hairpin
