| Amino Acid Sequence | VTSAGPEESD GDLSCVCVKT ISSGIHLKHI TSLEVIKAGR HCAVPQLIAT LKNGRKICLD RQAPLYKKVI KKILES | 
| Synonyms |  | 
| Accession Number | Q9Z126 | 
| GeneID | 56744 | 
| Summary |  | 
| Source | Escherichia coli. | 
| Molecular Weight | Approximately 8.2 kDa, a single non-glycosylated polypeptide chain containing 76 amino acids. | 
| Biological Activity | Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human neutrophils is in a concentration of 10-100ng/ml. | 
| Appearance | Sterile filtered white lyophilized (freeze-dried) powder. | 
| Formulation | Lyophilized from a 0.2 um filtered concentrated solution in 20 mM PB, 1.5 M NaCl, pH 7.4. | 
| Endotoxin | Less than 1 EU/ug of rMuPF-4/CXCL4 as determined by LAL method. | 
| Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions. | 
| Stability and Storage | Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution. |
