MIP-3 alpha/CCL20 Protein, Human
Based on 1 publication(s) in Google Scholar
MIP-3 alpha/CCL20 Protein, Human is a CC chemokine that attracts lymphocytes and mild neutrophils by binding to and acting on the chemokine receptor CCR6. It induces intracellular calcium mobilization and mediates cancer, various autoimmune diseases, and antimicrobial effects. MIP-3 alpha/CCL20 Protein, Human is a recombinant human CCL20 (A27-M96) expressed by E. coli.
- Species: Human
- Source: E. coli

Biological Activity
MIP-3 alpha/CCL20 Protein, Human is a CC chemokine that attracts lymphocytes and mild neutrophils by binding to and acting on the chemokine receptor CCR6. It induces intracellular calcium mobilization and mediates cancer, various autoimmune diseases, and antimicrobial effects. MIP-3 alpha/CCL20 Protein, Human is a recombinant human CCL20 (A27-M96) expressed by E. coli[1].
CCL20, also known as macrophage inflammatory protein 3 alpha (MIP-3-alpha) and liver-activated regulatory chemokine (LARC), is a small cytokine belonging to the CC chemokine family and is located on chromosome 2 in the human genome. It is expressed at lower levels in the thymus, testis, prostate and intestine. CCL20 binds to and acts as a chemokine receptor CCR6 and synergistically inhibits the function of CD8 T cells with CCR6. CCL20 has antimicrobial activity and has been implicated in autoimmune diseases such as inflammatory bowel disease, rheumatoid arthritis, and psoriasis, as well as oncological diseases. It can induce Tregs to invade tumor tissue, recruit dendritic cells to promote immunosuppression, and induce endothelial cell proliferation and neointima formation[1][2].
CCL20 (human, 0-50 μg/mL) inhibits B. abortus 2308 with the LD50 (the dose that achieves 50% reduction of CFU) > 50 μg/mL, effects on B. abortus RB51 in a dose-dependent manner with a LD50 of 8.7 μg/mL and demonstrates anti-E. coli activity with a LD50 of 1.5 μg/mL[3].
CCL20 is up-regulated in human colon adenocarcinoma cell lines stimulated by pro-inflammatory cytokines IL-1α and TNF-α and can function as an NF-κB target gene[4].
1.Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human T-lymphocytes is in a concentration range of 10.0-50.0 ng/mL.
2.Measured by its ability to chemoattract THP-1 human acute monocytic leukemia cells. The ED50 for this effect is ≤10.35 ng/mL, corresponding to a specific activity is ≥9.662×104 U/mg.
3.Measured by its ability to chemoattract BaF3 mouse pro-B cells transfected with human CCR6. The ED50 for this effect is <2 ng/mL, corresponding to a specific activity is >5×105 U/mg.
