Cat. Num. AAA4159674

• Gene Names: IL17A; IL17; CTLA8; IL-17; CTLA-8; IL-17A
• Purity: >95% as determined by SDS-PAGE
• Synonyms: IL17A; Recombinant Human IL17A; IL-17; CTLA-8; IL-17A; Cytotoxic T-lymphocyte-associated antigen 8; Recombinant Human Interleukin-17A (IL17A); IL17A active protein

• Host: E Coli
• Purity/Purification: >95% as determined by SDS-PAGE
• Form/Format: Lyophilized from a 0.2 um filtered solution in PBS (pH 7.5)
• Sequence Length: 155

• Bioactivity: The ED(50), as determined by the dose-dependent proliferation of induction of IL6 in primary human foreskin fibroblasts was found to be approximately 2.0 ng/mL, corresponding to a specific activity of > 5.0 x 10^5 units/mg
• Endotoxin Level: <1.0 EU/ug of recombinant protein as determined by the LAL method
• Reconstitution: A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
• Preparation and Storage: The lyophilized protein is stable for at least one year from date of receipt at-70 degree C. Upon reconstitution, this cytokine can be stored in working aliquots at 2-8 degree C for one month, or at-20 degree C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Related Product Information for IL17A active protein

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.

NCBI Description

The protein encoded by this gene is a proinflammatory cytokine produced by activated T cells. This cytokine regulates the activities of NF-kappaB and mitogen-activated protein kinases. This cytokine can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO). High levels of this cytokine are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis. [provided by RefSeq, Jul 2008]
