CCL8, also known as MCP-2, is a CC chemokine of the monocyte chemoattractant protein (MCP) family that plays key roles in allergic and inflammatory responses. CCL8 (MCP-2) has structural and functional similarity to other family members MCP-1 and MCP-3, and is often co-expressed with these chemokines in mononuclear cells. CCL8 is also constitutively expressed in the skin and lymph nodes of mice.
Mouse CCL8 induces a chemotactic migration of a population of differentiated Th2 cells enriched in IL-5 and IL-25 receptors by binding to the CCR8 receptor. Recent studies have established CCL8 as a critical ligand for driving CCR8-dependent Th2 cell trafficking into the skin, which in conjunction with locally recruited eosinophils drives chronic cutaneous allergic inflammation. CCL8 expression by suprabasal buldge cells has also been experimentally shown to negatively regulate the population of mouse hair follicles by Langerhans cells, further underscoring this chemokines central contributions to maintaining cutaneous immunity.
- Host Species
- E. coli
- Mouse CCL8, amino acids Gly24-Pro97 (Accession# NM_021443.3) was expressed in E. coli.
- Molecular Mass
- The 74 amino acid recombinant protein has a predicted molecular mass of approximately 8.48 kD. The DTT-reduced protein migrates at approximately 11 kDa and non-reduced protein migrates at approximately 12 kD by SDS-PAGE. The N-terminal amino acid is Gly.
- >95%, as determined by Coomassie stained SDS-PAGE.
- Lyophilized in sterile-filtered PBS, pH 7.2, containing 1% BSA, 0.09% sodium azide, and protease inhibitors.
- Storage & Handling
- Immediately upon receipt, store unopened vials between 2°C and 8°C and use within 12 months from date of receipt. Prior to use, reconstitute the lyophilized powder with 0.2 ml of PBS containing a carrier protein (e.g., 1% BSA, protease free), pH 7.4. Re-cap vial, vortex. Allow the reconstituted standard to sit at room temperature for 15 minutes, vortex again to mix completely. The reconstituted standard stock solution can be aliquoted into polypropylene vials and stored at -70°C for up to one month. Do not re-use diluted standards. Use a manual defrost freezer and avoid repeated freeze thaw cycles.
ELISA - Quality tested
- Recommended Usage
Each lot of this protein is quality control tested by ELISA assay. For use as an ELISA standard, a standard curve comprised of doubling dilutions from 15.6 to 1,000 pg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
This mouse CCL8 (MCP-2) protein is useful as a standard for mouse CCL8 (MCP-2) sandwich ELISA, using unlabeled A16070K antibody (Cat. No. 536902) as capture and biotinylated Poly5352 antibody (Cat. No. 535203) as detection.
Fibroblast, endothelial cells, monocytes, macrophages, and skeletal muscle cells.
- CCL8 chemoattracts monocytes, T cells, NK cells, mast cells, eosinophils, and basophils. CCL8 is induced by IL-1β, IFNβ, IFNγ, dsRNA, virus, ConA, and anti-CD2. The induction of CCL8 by IFNγ synergizes with the TLR ligands peptidoglycan (TLR2), dsRNA (TLR3), and LPS (TLR4).
- Monocytes, T cells, NK cells, mast cells, eosinophils, and basophils.
