描述

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, Human (CHO, His) is a recombinant human IL-17A protein with His tag at the C-terminus and is expressed in CHO cells. It consists of 132 amino acids (G24-A155).

研究背景

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 human IL-17A shares 63.23% amino acid sequence identity with mouse and 61.90% identity with rat.
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].

体外研究
(In Vitro)

IL-17A (100 ng/mL; 24 h) inhibits the expression of thymic stromal lymphopoietin (TSLP) in human primary keratinocytes[5].
IL-17A (0.1–100 ng/mL; 0-24 h) significantly potentiates TNF-α-induced IL-8 protein secretion and gene expression in a concentration- and time-dependent manner[6].

生物活性

The ED50 is <10 ng/mL as measured by NHDF cells, corresponding to a specific activity of >1 × 105 units/mg.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×
C1   V1   C2   V2

The specific active calculator equation

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Active (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
