|Description||The originally described IL-17 protein, now known as IL-17A, is a homodimer of two 136 amino acid chains, secreted by activated T-cells that act on stromal cells to induce production of proinflammatory and hematopoietic bioactive molecules. Today, IL-17 represents a family of structurally-related cytokines that share a highly conserved C-terminal region but differ from one another in their N-terminal regions and in their distinct biological roles. The six known members of this family, IL-17A through IL-17F, are secreted as homodimers. IL-17A exhibits cross-species bioactivity between human and murine cells. Recombinant human IL-17A is a 31.3 kDa disulfide-linked homodimer of two 137 amino acid polypeptide chains.|
|BiologicalActivity||Assay #1: The ED50 as determined by the dose-dependent induction of IL-6 in primary human foreskin fibroblasts was found to be approximately 2 ng/ml. |
Assay #2: Measured by its ability to induce IL-6 production by NHDF cells.
|Authenticity||Verified by N-terminal and Mass Spectrometry analyses (when applicable).|
|Endotoxin||Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg).|
|Protein Content||Verified by UV Spectroscopy and/or SDS-PAGE gel.|
|Precautions||Animal-Free Recombinant Human IL-17 (IL-17A) is for research use only and not for use in diagnostic or therapeutic procedures.|
