ActoFactor™ Recombinant Mouse Platelet factor 4
- Specification
Cat.No.
CSC-CTK0754
Description
Platelet Factor-4 is a 70 amino acid protein that is released from the alpha-granules of activated platelets and binds with high affinity to heparin. Its major physiologic role appears to be neutralization of heparin-like molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, PF4 probably has a role in inflammation and wound repair. Oncostatin A is a member of the CXC chemocinfamily. Human PF-4 is used for the proof of heparin-induced thrombocytopenia. Furthermore, it is used as an inhibitor of angiogenesis during tumor therapy. Mouse recombinant CXCL4 produced in E. coli is a single, non-glycosylated polypeptide chain containing 73 amino acids and having a molecular mass of 8.2 kDa.

Formulation
Sterile-filtered, white, lyophilized (freeze-dried) powder. Lyophilized from a concentrated (1 mg/ml) protein solution in 1X PBS (pH 7.4).
Reconstitution
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
