商品介绍
Species: Human
Host Species: E. coli
MW: 8 kDa
Genbank #: P02775
a.a: 59–128
Background:
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 positions.
Description:
Recombinant NAP-2 is a disulfide-linked monomeric protein consisting of 71 amino acid residues and migrates as an approximately 8 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human NAP-2 (CXCL7) mature chain was expressed in E. coli.
UniProt
P02775
Synonym(s):
NAP2, CXCL7, NAP-2, Pro-Platelet Basic Protein, Chemokine (C-X-C Motif) Ligand 7, B-TG1, beta-TG, LDGF, PPBP, Neutrophil-Activating Peptide 2
Purity:
≥98% by SDS-PAGE and HPLC
Endotoxin Level:
<0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity:
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 µm filtered 20 mM Phosphate buffer, 100 mM NaCl, pH 7.5.
Format:
lyophilized protein
Reconstitution:
Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability:
The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
