Product Specs

Introduction
CCL-20, also known as MIP-3 alpha, is a chemotactic factor that attracts lymphocytes and neutrophils, but not monocytes. It inhibits the proliferation of myeloid progenitor cells and plays a crucial role in the development and function of mucosal lymphoid tissues by directing lymphocytes and dendritic cells toward epithelial cells. Notably, C-terminal processed forms of CCL-20 exhibit equivalent chemotactic activity on leukocytes. CCL-20 also possesses antibacterial properties against E. coli (ATCC 25922) and S. aureus (ATCC 29213). The transcription of the CCL-20 gene is activated by H. pylori, which in turn activates NF-kappaB via an intracellular signaling cascade involving IkappaB kinase and NF-kappaB-inducing kinase. MIP-3 alpha is implicated in chemokine-mediated lymphocyte trafficking during gastric inflammation induced by Helicobacter infection. CCL-20 expression contributes to the recruitment of CD45R0-positive T cell subsets to the intestinal lamina propria. Furthermore, MIP-3A promotes pulpal inflammation by recruiting C-C motif Receptor 6-expressing lymphocytes. Vaginal epithelial cells, in response to factors present in semen, secrete MIP-3 alpha, thereby enhancing Langerhans cell recruitment during HIV transmission.
Description
Recombinant Human MIP-3 Alpha, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 70 amino acids. It has a molecular weight of 8 kDa. The purification process of MIP-3a involves proprietary chromatographic techniques.
Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation
Lyophilized from a 0.2 µm filtered solution in 20mM Phosphate Buffer (PB), pH 7.4, containing 150mM Sodium Chloride (NaCl).
Solubility
To reconstitute the lyophilized MIP-3 Alpha, it is recommended to dissolve it in sterile 18 MΩ-cm H2O at a concentration of at least 100 µg/ml. This solution can be further diluted in other aqueous solutions as needed.
Stability
Lyophilized MIP-3a remains stable at room temperature for up to 3 weeks; however, it is recommended to store it desiccated at a temperature below -18°C. After reconstitution, CCL20 should be stored at 4°C for 2-7 days. For long-term storage, it is recommended to store it below -18°C. To ensure optimal stability during long-term storage, consider adding a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
Purity
The purity of MIP-3a is greater than 97.0%, as determined by: (a) Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) analysis. (b) Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE) analysis.
Biological Activity
The biological activity of MIP-3a is assessed by its chemotactic effect on human T lymphocytes. This is determined using a concentration range of 10.0 - 50.0 ng/ml, which corresponds to a specific activity of 20,000 - 100,000 units/mg.
Synonyms

Product Science Overview

Expression and Regulation

CCL20 is expressed in various tissues, including the liver, lungs, lymph nodes, and peripheral blood lymphocytes . Its expression is strongly upregulated by inflammatory signals and downregulated by the anti-inflammatory cytokine IL-10 .

Structure and Molecular Characteristics

Human recombinant CCL20 is a protein consisting of 70 amino acids with a molecular weight of approximately 8 kDa . It contains four highly conserved cysteine residues, which are characteristic of CC chemokines . The protein is typically produced in an E. coli expression system and purified to a high degree of purity (>98%) for research purposes .

Function and Mechanism of Action

CCL20 signals through the G protein-coupled receptor CCR6 . It acts as a chemoattractant, primarily attracting lymphocytes and dendritic cells to sites of inflammation . This chemokine is particularly important in mucosal immunity, where it helps to recruit immune cells to the mucosal surfaces of the gut, lungs, and skin .

Clinical and Research Applications

Due to its role in immune cell recruitment, CCL20 is a significant focus of research in various inflammatory and autoimmune diseases. It is also studied in the context of cancer, where it may play a role in tumor progression and metastasis .

Storage and Handling

Recombinant human CCL20 is typically supplied as a lyophilized powder and should be reconstituted in sterile, distilled water . For long-term storage, it is recommended to keep the reconstituted protein at -20°C and avoid repeated freeze/thaw cycles .
