Cat. No.	Z100725
Name	Recombinant Human NAP-2 (PPBP) (CXCL7)
Description	The chemokine neutrophil- activating peptide 2 (NAP-2) is a 70-amino acid residue polypeptide that is formed from platelet-derived precursors by proteolytic processing. Mature NAP-2 stimulates various effector functions of polymorphonuclear neutrophil granulocytes (PMN) including directed chemotactic migration, exocytosis of lysosomal enzymes and secondary granule contents, and up-regulation of adhesion receptors. NAP-2 has been assigned to a subfamily now termed alpha-chemokines. The alpha-chemokines contain four cysteine residues at highly conserved positions which enclose the core region of the molecules. The first two cysteines are separated by a single amino acid, forming a motif (CXC) that distinguishes the alpha-chemokine from the beta-chemokine subfamily, where these cysteines are in directly adjacent position.

Endotoxin Level	<1.0 EU/µg of recombinant protein as determined by the LAL method.
Purity	>95% as determined by SDS-PAGE
Formulation	Lyophilized from a 0.2 μm filtered 20 mM PB,100 mM NaCl solution pH 7.5.
Function	Determined by its ability to chemoattract human monocytes using a concentration range of 2.0-40.0 ng/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. Z100725

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.
