Protein construction description

A DNA sequence encoding the human IL-17A protein (Q16552) (Gly 24-Ala 155) was expressed with tag free.

Accession

Q16552

Protein construction

IL-17A (24-155)

Source

HEK293

Bio Activity

Measured by its ability to induce IL-6 secretion by NIH/3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 3-10 ng/mL.

Purity

>90% as determined by SDS-PAGE.

Endotoxin

Less than 1.0 EU per μg by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4, 5% Trehalose, 5% mannitol.

Species

Human

Background

Interleukin‑17A (IL‑17A), also known as CTLA‑8, is a 15‑20 kDa glycosylated cytokine that plays an important role in anti‑microbial and chronic inflammation. The six IL‑17 cytokines (IL‑17A‑F) are encoded by separate genes but adopt a conserved cystine knot fold. Mature human IL‑17A shares 60% amino acid sequence identity with mouse and rat IL‑17A. IL‑17A is secreted by Th17 cells, gamma /δ T cells, iNKT cells, NK cells, LTi cells, neutrophils, and intestinal Paneth cells. It forms disulfide‑linked homodimers as well as disulfide‑linked heterodimers with IL‑17F. IL‑17A exerts its effects through the transmembrane IL‑17 RA in complex with IL‑17 RC or IL‑17 RD. Both IL‑17 RA and IL‑17 RC are required for responsiveness to heterodimeric IL‑17A/F. IL‑17A promotes protective mucosal and epidermal inflammation in response to microbial infection. It induces chemokine production, neutrophil influx, and the production of antibacterial peptides.

Usage guide

Shipping

In general, recombinant proteins are provided as lyophilized powder which are shipped with blue ice. Bulk packages of recombinant proteins are provided as frozen liquid which are shipped with dry ice.

Storage

Please avoid repeated freeze-thaw cycles. Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃ It is recommended that aliquot the reconstituted solution to minimize freeze-thaw cycles.
