General description

Protamine sulfate is a cationic polypeptide having a molecular weight of 5 kDa, isolated from salmon sperm.

Application

Protamine sulfate has been used in the transduction of
  • lentiviruses into human embryonic 293T cells
  • shRNA into mesenchymal stem cells/marrow stromal cells (MSC)
  • lenti Sca1-OCT4 plasmid into human cord blood hematopoietic progenitor CD34+ cells

Biochem/physiol Actions

Alkaline protamine binds to negatively charged heparin. Use of protamine during cardiovascular surgery sometime triggers anaphylactic reactions.
Protamine facilitates direct transfection of microbial cells, and of human cells using cationic liposomes. Protamine effectively neutralizes the anticoagulation effects of heparin.

Questions

  1. In what solution can this particular protamine sulfate be dissolved? Sterile water, PBS, DMSO,...?

    1 answer
    1. This product is not tested for solubility. However, other Protamine sulfate products currently available are dissolved initially in 6N Hydrochloric acid at 25 mg/mL. This stock solution may then be diluted out with aqueous buffer or medium. In addition, a brief search of the literature reveals that this material may also be prepared by dissolving in HPLC grade water to a concentration of 10mg/ml. A stock solution was diluted to a final working concentration in growth media of 10?g/ml and stored at -20°C. This information has not been validated.
