Cat. No.	Z200309
Name	Recombinant Mouse CXCL4 (PF4)
Description	Platelet factor 4 (PF4/CXCL4) is an ELR− tetrameric, cationic chemokine that constitutes 25% of the protein in platelet α-granules. It is also found bound to the luminal vascular endothelial surface. Although platelets represent the primary source of PF4, it is also expressed at lower levels in other cells of the immune system including cultured T cells, monocytes, and endothelial and smooth muscle cells.
Organism	Mouse (M. musculus)
Storage Condition	Ice Pack
Unit quantity	1.0 mg
Family	Chemokine-alpha Family (CXC)
Tag	Tag Free
Gene Symbol	PF4
Accession Number	Q9Z126
Source	E. coli
Species	Mouse (M. musculus)
Appearance	Lyophilized Powder
Molecular Weight	9 kDa
Endotoxin Level	<1.0 EU/µg of recombinant protein as determined by the LAL method.
Purity	>95% as determined by SDS-PAGE
Formulation	Recombinant mouse PF4/CXCL4 was lyophilized from a 0.2 μm filtered concentrated (1.0 mg/mL) solution in 20 mM PB, 1.5M NaCl pH 7.4.
Function	Determined by its ability to inhibit human FGF-basic-dependent proliferation of NR6R-3T3 mouse fibroblasts. The ED50 for this effect is typically 5.0-15 μg/mL.
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Shipping Conditions	This lyophilized protein is shipped at ambient temperature. Cold packs may be used if transit temperatures are elevated. The product remains stable during normal shipping conditions.
Storage	Upon receipt, store lyophilized protein at –70°C for long-term storage. Short-term storage at –20°C is acceptable if necessary. Once reconstituted, store at 2–8°C for up to 1 month, or at –20°C for up to 6 months. Avoid repeated freeze/thaw cycles.
Usage	For research use only. Not for diagnostic or therapeutic use.
Material Citation	If use of this material results in a scientific publication, please cite the material in the following manner: Applied Biological Materials Inc, Cat. No. Z200309

How do I choose the right growth factor for my experiment?

Cell type: Different cells respond to different growth factors. Choose a growth factor that promotes the growth or differentiation of your target cell type.
Desired outcome: Whether you are studying proliferation, differentiation, or survival, different growth factors will promote different cellular behaviors.
Concentration and formulation: Different experiments may require varying concentrations of growth factors.

	What is the shelf life and storage condition of this product?
	The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
