Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation (By similarity).Reference: "Significantly elevated expression of PF4 (platelet factor 4) and eotaxin in the NOA mouse, a model for atopic dermatitis."Watanabe O., Natori K., Tamari M., Shiomoto Y., Kubo S., Nakamura Y.J. Hum. Genet. 44:173-176(1999) Purity: Greater than 90% as determined by SDS-PAGE.Storage Buffer: Tris-based buffer,50% glycerol Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
