Descripción general

Platelet factor-4 (PF-4) is a CXC chemokine that is expressed in megakaryocytes and stored in the alpha-granules of platelets. The gene encoding this protein is localized on human chromosome 4. Recombinant human PF-4 is a 7.8kDa protein containing 70 amino acid residues, including the four highly conserved residues present in CXC chemokines.

Acciones bioquímicas o fisiológicas

Platelet factor-4 (PF-4) is chemotactic towards neutrophils and monocytes and has been shown to inhibit angiogenesis. This protein associates with heparin and neutralizes it. It also neutralizes various negatively charged proteoglycans.

Reconstitución

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

A large scale purification procedure for the human platelet factor 4 proteoglycan carrier molecule has been developed. A yield of 46% and a 33,000-fold purification have been achieved, using poly-L-lysine-Sepharose affinity column chromatography, PF4-agarose affinity column chromatography, and Bio-Gel A-0.5m

Unstimulated monocytes rapidly undergo physiological changes resulting in programmed cell death (apoptosis) while stimuli promoting differentiation of these cells into macrophages were shown to inhibit apoptotic processes. In the present study, we report that the platelet-derived alpha-chemokine platelet factor 4
