Recombinant Human NAP-2 (PPBP) (CXCL7)

Cat. No.
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.

Recombinant Human Neutrophil Activating Peptide-2 (PPBP)
Gene Symbol PPBP
Gene ID 5473
Accession Number P02775
Source E. coli
Species Human (H. sapiens)
Appearance Lyophilized Powder
Molecular Weight 8 kDa
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.
Storage 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.
Usage For research use only. Not for diagnostic or therapeutic use.
