Full Name	Neutrophil Activating Protein-2 Human Recombinant (CXCL7)
Synonyms	Platelet basic protein, PBP, Small inducible cytokine B7, CXCL7, Leukocyte-derived growth factor, LDGF, Macrophage-derived growth factor, MDGF, pro-platelet basic protein (chemokine (C-X-C motif) ligand 7), TC1, TC2, TGB, TGB1, B-TG1, CTAP3, NAP-2, SCYB7, THBGB, LA-PF4, THBGB1, Beta-TG, CTAPIII, CTAP-III.
Source	E. coli
Amino Acid Sequence	The sequence of the first five N-terminal amino acids was determined and was found to be Ala-Glu-Leu-Arg-Cys.
Molecular Weight	Neutrophil Activating Protein-2 Human Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 70 amino acids and having a molecular mass of 7.6kDa.
Purity	>95% as determined by SDS-PAGE and HPLC
Endotoxin	Endotoxin level was found to be ≤ 0.1 ng/µg(1EU/µg) by LAL gel clot method.
Formulation	Lyophilized from sterile water containing no additives.
Reconstitution	To reconstitute the protein, add sterile water to the lyophilized protein and make a preparation with a concentration ≥0.1mg/ml. The preparation can be diluted into other appropriate buffers if necessary. Be cautious and avoid potential contamination with bacteria and endotoxin
Stability	The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles.
Biological Activity	The specific activity as determined by the ability of NAP2 to chemoattract human neurotrophils using a concentration of 1-10ng/ml corresponding to a Specific Activity of 10,000-100,000IU/mg.
Usage	LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes.
