简介
The S100A9 protein is a calcium and zinc binder that plays a critical regulatory role in inflammation and immune responses. Its diverse functions include induction of neutrophil chemotaxis, adhesion, enhanced bactericidal activity through SYK, PI3K/AKT and ERK1/2 activation, and promotion of phagocytosis. S100A9 Protein, Cynomolgus (His) is the recombinant cynomolgus-derived S100A9 protein, expressed by E. coli , with N-His labeled tag.

Protein Description
S100A9, a member of the S100 protein family, is a calcium-binding protein that plays a crucial role in various biological processes, including inflammation, cell proliferation, and apoptosis. It is predominantly expressed in myeloid cells and has been identified as a key player in the immune response, particularly in chronic inflammatory diseases, autoimmune disorders, and cancer. Research has shown that S100A9 can form heterodimers with S100A8, enhancing its biological activity and contributing to the formation of pro-inflammatory complexes. The dysregulation of S100A9 expression is associated with several pathological conditions, including rheumatoid arthritis, inflammatory bowel disease, and various types of malignancies. Given its significant role in mediating inflammatory responses, S100A9 has emerged as a potential biomarker for disease diagnosis and prognosis, as well as a target for therapeutic interventions. Recombinant S100A9 protein is essential for studying its structure-function relationships, understanding its interactions with other proteins, and exploring its mechanism of action in inflammatory pathways. The production and characterization of S100A9 recombinant protein have garnered attention for their implications in developing novel therapeutic strategies aimed at modulating inflammation and improving outcomes in related diseases. Thus, the investigation of S100A9 recombinant protein serves as a critical avenue in biomedicine, offering insights into its role as a potential therapeutic target and advancing our understanding of inflammatory mechanisms.
