表達區(qū)間及表達系統(tǒng)（Source）
Human IL-17A&IL-17F Heterodimer Protein, Twin Strep&His Tag (ILF-H52W6) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Ala 155 (IL-17A) & Arg 31 - Gln 163 (IL-17F) (Accession # Q16552-1 (IL-17A) & Q96PD4-1 (IL-17F)). Two sequential affinity purification steps were used to ensure exact 1:1 molar ratio of IL17A＆IL17F heterodimer.
Predicted N-terminus: Trp (IL-17A) & His (IL-17F)
蛋白結(jié)構(gòu)（Molecular Characterization）
Human IL-17A&IL-17F Heterodimer Protein, Twin Strep&His Tag, produced by co-expression of IL-17A and IL-17F, has a calculated MW of 18.5 kDa (IL-17A) and 16.8 kDa (IL-17F). Subunit IL-17A is fused with a Twin Strep tag at the N-terminus and subunit IL-17F is fused with a polyhistidine tag at the N-terminus. The protein migrates as 19-27 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素（Endotoxin）

背景（Background）
白細胞介素-17A（IL17A）也被稱為細胞毒性T淋巴細胞相關(guān)抗原8（CTLA8），這是一種由活化的T細胞產(chǎn)生的促炎細胞因子。IL17A可以調(diào)節(jié)NF-κB和絲裂原活化蛋白激酶的活性。此外，IL17A可以刺激IL6和環(huán)氧化酶-2（PTGS2/COX-2）的表達，并增強一氧化氮（NO）的產(chǎn)生。此外，IL17A既有糖基化的形式，也有非糖基化形式。高水平的IL-17與幾種慢性炎癥性疾病有關(guān)，包括類風(fēng)濕性關(guān)節(jié)炎、銀屑病和多發(fā)性硬化癥。
