Interleukin-17A (IL-17A), also known as CTLA-8, is a glycosylated cytokine that plays an important role in anti-microbial and chronic inflammation. Mature rat IL-17A shares 60% and 89% amino acid sequence identity with human and mouse IL-17A, respectively. 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-17RA in complex with IL-17RC or IL-17RD. Specifications Synonyms CTLA-8; IL17; IL17A; IL-17CTLA-8; interleukin 17A Uniprot No. Q16552-1 Source Recombinant Biotinylated Human IL-17A/CTLA-8 Protein is expressed from HEK293 Cells with His tag and Avi tag at the C-terminal. It contains Gly24-Ala155. Molecular Weight The protein has a predicted MW of 18.2 kDa. Due to glycosylation, the protein migrates to 16-30 kDa based on Tris-Bis PAGE result. Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder. Purity > 95% as determined by SDS-PAGE Endotoxin < 1.0 EU per 1μg of the protein by the LAL method. Formulation Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100μg/mL is recommended. Dissolve the lyophilized protein in distilled water. Storage The products are shipped with ice pack and can be stored at -20℃ for 1 year. 2-7 days, 2 to 8 °C under sterile conditions after reconstitution.3 -6 months, -20 to -80°C under sterile conditions after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles. Note 1. For your safety and health, please wear lab coats and disposable gloves for operation. 2. For research use only! Product Data.
