The founding member of the IL17 family of cytokines, IL17A plays an important role in antimicrobial and chronic inflammation. All the six IL17 cytokines (IL17A-F) share a cystine knot fold and are secreted as homodimers. Mature human IL17A shares 60% amino acid sequence identity with rat and mouse IL17A. IL17 cytokines bind to two receptors; IL17RA and IL17RC that together form a heterodimer. The receptor heterodimer is preferred by IL17 ligands, and thus, either IL17RA or IL17RC knockouts completely abolish IL17 signalling. Recombinant human IL17A is a non-glycosylated, 32 kDa disulfide-linked homodimer.
Aliases- IL-17, CTLA-8, IL-17A, Cytotoxic T-lymphocyte-associated antigen 8
- Recombinant Human Interleukin-17A (IL17A)
Formulation- Lyophilized from a 0.2 µm filtered solution in PBS (pH 7.5)
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
