IL-17A Protein, Marmoset
Based on 1 Customer Validation
IL-17A is a homodimeric cytokine and plays a critical role in host defense mechanisms against many bacterial and fungal pathogens as well as allergic and autoimmune responses. IL-17A induces the production of antimicrobial peptides, cytokines, chemokines, and matrix metalloproteinases. IL-17A Protein, Marmoset is a recombinant marmoset IL-17A protein is expressed in E. coli. It consists of 134 amino acids (I20-A153).
- Species: Marmoset
- Source: E. coli
-
Storage:Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Description
IL-17A is a homodimeric cytokine and plays a critical role in host defense mechanisms against many bacterial and fungal pathogens as well as allergic and autoimmune responses. IL-17A induces the production of antimicrobial peptides, cytokines, chemokines, and matrix metalloproteinases[1][2]. IL-17A Protein, Marmoset is a recombinant marmoset IL-17A protein is expressed in E. coli. It consists of 134 amino acids (I20-A153).
Background
Interleukin-17A (IL-17A), also known as CTLA-8, belongs to the IL-17 cytokine family. IL-17A is expressed in memory Th17 cells and is a product of memory CD4+ T cells. IL-17A is also produced by a wide variety of immune cells, including CD8+ T cells, γδT cells, natural killer T (NKT) cells, monocytes, and neutrophils[1][2][3].
The rhesus macaque IL-17A shares 90.20% amino acid sequence identity with human and 63.40% identity with mouse.
IL-17A plays a critical role in host defense mechanisms against many bacterial and fungal pathogens as well as allergic and autoimmune responses. IL-17A induces the production of antimicrobial peptides (defensins and S100 proteins), cytokines (IL-6, G-CSF, and GM-CSF), chemokines (CXCL1, CXCL5, IL-8, CCL2, and CCL7), and matrix metalloproteinases (MMP1, MMP3, and MMP13). IL-17A is detrimental in viral infection through promoting neutrophilic inflammation. IL-17A is a homodimeric cytokine and shares similar biological activities with IL-17F. IL-17A binds to IL-17RA with high affinity, and IL-17RA is required for the biological activity of IL-17A. In tumorigenesis, IL-17A recruits myeloid derived suppressor cells (MDSCs) to dampen anti-tumor immunity. IL-17A also enhances tumor growth in vivo through the induction of IL-6[1][2].
IL-17A can be used for the research of autoimmune diseases, infection and cancer[1][4].
Verified Bioactivity
Measured by its ability to induce IL-6 secretion by NIH-3T3 mouse embryonic fibroblast cells. The ED50 for this effect is 1.475 ng/mL, corresponding to a specific activity is 6.78×105 U/mg.
