SJB05
25μg
Description:
Recombinant human interleukin-8 is recombinantly expressed in yeast and contains 72 amino acids without glycosylation sites.
Source: Yeast.
Molecular Mass: Approximately 8.3kD.
Purity: ≥97%.
Endotoxin Level: <1EU/µg, determined by the LAL method.
Biological Activity:
Measured by inhibiting cAMP ability of HEK293/CXCR1 cell. The ED50 for this effect is typically 0.5-10ng/ml.
Formulation:
Lyophilized from a 0.2μm filtered solution in PBS containing 0.1% HSA, pH7.4.
Reconstitution:
It is recommended to centrifuge at 10,000rpm for 30-60 sec or 3000rpm for 5 min before opening the tube, and then reconstitute with 0.2ml sterile water.
Storage:
Lyophilized samples are stable for 36 months from date of manufacture at -20℃ to -70℃.
Upon reconstitution, this cytokine can be stored under sterile conditions at 2- 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer for three months without detectable loss of activity.
Avoid repeated freeze-thaw cycles.
For Laboratory Use Only.
