This product is a research-grade, unconjugated recombinant analog of secukinumab, a fully human IgG1-kappa monoclonal antibody directed against human interleukin-17A (IL-17A, UniProt Q16552). It is a non-therapeutic biosimilar intended strictly for research use only; it is not the clinical drug and is not for human or veterinary use. Reproducing the published antigen specificity and human IgG1-kappa framework of the originator, it is a useful reference reagent for studying IL-17A biology, benchmarking IL-17A-targeting molecules, and serving as an isotype-matched, well-defined positive control in binding and neutralization assays. Because it is offered at research scale, it supports method development, assay standardization, and in-vitro and preclinical workflows where a consistent, well-characterized anti-IL-17A antibody is needed. It is available in bulk quantities (milligram to gram) and in low-endotoxin grades (research grade less than 1 EU/mg; ultra-low less than 0.5 EU/mg) suitable for cell-based and sensitive functional experiments. Format is unconjugated, leaving it open for downstream labeling, immobilization, or engineering.
Interleukin-17A (IL-17A) is a pro-inflammatory cytokine and the founding member of the IL-17 family. It is produced chiefly by Th17 CD4+ T cells, but also by CD8+ T cells, gamma-delta T cells, innate lymphoid cells, natural killer cells, and neutrophils. IL-17A is secreted as a disulfide-linked homodimer and can also form heterodimers with IL-17F. It signals through a receptor complex of IL-17RA and IL-17RC, recruiting the adaptor ACT1 to drive NF-kB, MAPK, and C/EBP signaling. This induces expression of pro-inflammatory cytokines, chemokines (including CXCL1, CXCL8/IL-8), antimicrobial peptides, and matrix metalloproteinases from epithelial cells, fibroblasts, and keratinocytes. IL-17A supports host defense against extracellular bacteria and fungi, but its dysregulation is central to autoimmune and inflammatory diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis, making it a validated therapeutic and research target.
