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.
Catalog #E2800
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]
Molecular Weight8.0kD
