| 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. |
| Accession | P02775 |
| Functions | Determined by its ability to chemoattract human monocytes using a concentration range of 2.0-40.0 ng/mL. |
| Formulation | Lyophilized from a 0.2 ?m filtered 20 mM PB,100 mM NaCl solution pH 7.5. |
| Solubility | 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. |
| Appearance | Lyophilized Powder |
| Molecular Weight | 8 |
| Purity | >95% as determined by SDS-PAGE |
| Concentration | <1.0 EU/μg of recombinant protein as determined by the LAL method. |
| Shipping Condition | Ambient Temperature |
| Storage Condition | 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. |
