Human Cytokine/Growth Factor/Chemokines Sample Spec sheets (subject to change without notice):

DATA SHEET:recombinant Human INTERLEUKIN-8 (72 A.A.)

-Interleukin-8 (IL-8) is an 8.0 kDa protein 72 amino acid residues. It promotes neutrophil chemotaxis and degranulation. The 72 amino acid IL-8 is the predominant form secreted by monocytes and lymphocytes.

Catalog#: RDI-208M

Package Size: 25 micrograms $231.00    $219.00/vial 2 or more any combination

                       Mini-Pack: cat#RDI-208p $94.00/5ug

                    -inquire for custom sizes/bulk packaging

Supplied: Lyophilized powder with no additives.

Source: E. Coli

Purity: >98% by SDS-Page analysis and HPLC analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug) of IL-8.

Reconstitution: The lyophilized IL-8 should be reconstituted in water to a concentration of 0.1-1.0mg/ml. All to set at least 30 minutes, then mix well. Centrifuge for 1-2 minutes at 1000 rpm to concentrate material in vial. When possible, addition of BSA or HSA (up to 0.1%) to cytokine solutions diluted below 50ug/ml is advisable). This solution can be diluted into other buffered solutions and stored 4 DEG C for up to 1 week or stored at -20 DEG C for future use.

Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored dessicated at -20 Deg C. Reconstituted IL-8 should be stored in working aliquots at -20DEG C. AVOID FREQUENT FREEZE THAW CYCLES.

Reactivity: Rec Human Il-8 produces chemotaxis over a wide concentration range in an assay using human peripheral blood neutrophils. Significant chemotaxis was achieved using a concentration of 10-100 ng/ml.
