Supplied as a lyophilized powder. No additives. Reconstitute with ddH2O.

Human interleukin-8 (IL-8) is an 8.4kD protein containing 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.

Source:
Recombinant protein corresponding to human IL-8 expressed in E. coli.

Biological Activity:
Determined by its ability to chemoattract human peripheral blood neutrophils using a concentration range of 10.0-100.0ng/ml.
