Recombinant Human Interleukin-8 (CXCL8), partial (Active)

Interleukin-8; IL-8; C-X-C motif chemokine 8; Chemokine (C-X-C motif) ligand 8; Emoctakin; Granulocyte chemotactic protein 1 (GCP-1) ; Monocyte-derived neutrophil chemotactic factor (MDNCF) ; CXCL8; IL8

Measured by its binding ability in a functional ELISA. Immobilized Human CXCL8 at 2 μg/mL can bind Anti-CXCL8 recombinant antibody. The EC50 is 43.95-46.76 ng/mL.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
