Descripción

Descripción general

Protamine sulfate (PS), a polycationic, positively charged protein[1] is mostly made up of poly(l-arginine).[2] It is obtained from salmon sperm protein.[1]

Aplicación

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 generation of protamine silica nanocomposites.[3]

Acciones bioquímicas o fisiológicas

Protamine sulfate is a small cationic protein that binds and precipitates DNA. Neutralizes the anticoagulant activity of heparin. Inhibits lipoprotein lipase.

Protamine sulfate is highly preferred in cardiovascular surgical procedures to reverse the anticoagulant properties of heparin.[4] It is used for biomedical and biotechnological applications due to its biodegradablity.[2]

Calidad

May contain insolubles as well as histones.
