Epithelial Neutrophil Activating Peptide-78 (ENA-78) is a recently discovered chemoattractant and activator for neutrophils, belonging to the IL-8 subgroup of the C-X-C family of chemokines. Human ENA-78 is an 8.0kDa protein containing 74 amino acid residues.||Formulation: Lyophilized protein with no additives. The protein may appear as a haze or film which is difficult to see at the bottom of the vial.||Stability: The lyophilized protein, though stable at room temperature, is best stored desiccated below 0°C. Reconstituted human ENA-78 should be stored in working aliquots at -20°C.||Purity: ≥ 98% by SDS-PAGE and HPLC||Endotoxin: ≤ 0.1ng/ug ||Reconstitution: The lyophilized ENA-78 is soluble in water and most aqueous buffers. The lyophilized protein can be reconstituted in water to a concentration of 0.1-1mg/ml. It is recommended that further dilutions be made into buffer containing carrier protein or medium containing serum.||Biological Activity: Human ENA-78 produces chemotaxis over a wide concentration range in an assay using human peripheral blood neutrophils. Significant chemotaxis was achieved using a concentration of 50ng/ml.||Responding Cells: Neutrophils||Concentration Range: 25-500ng/ml [for most in vitro applications]||AA Sequence:AAVLRELRCV CLQTTQGVHP KMISNLQVFA IGPQCSKVEVVASLKNGKEICLDPEAPFLK KVIQKILDGG NKENImportant Note: This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological.
