Description

CLL24 was initially cloned from a library of activated macrophages, and using human eosinophils, it was shown that it binds to the receptor of eotaxin-1 (CCL11) and MCP-4 (CCL13). In addition, CCL24 shares the CCR3 receptor with CCL26, CCL5, and CCL7. Eotaxin/CCR3 expression has been studied extensively in the pathogenesis of asthma and allergy. In addition, the eotaxin/CCR3 axis has been associated to additional inflammatory and autoimmune disorders including inflammatory bowel disease, multiple sclerosis, eosinophilic esophagitis, and rheumatoid arthritis. CCL24 has also been associated to neovascular age related macular degeneration.

Product Details

Source
Mouse CCL24, amino acids Ile24-Val119 (Accession# NM_002991.2) was expressed in E.coli.
Molecular Mass
The 96 amino acid recombinant protein has a predicted molecular mass of approximately 10.6 kD. The DTT-reduced protein migrates at approximately 12 kD and non-reduced protein migrates at 14 kD by SDS-PAGE. The N-terminal amino acid is Isoleucine.
Purity
>98%, as determined by Coomassie stained SDS-PAGE.
Formulation
0.22 µm filtered protein solution is in PBS.
Endotoxin Level
Less than 0.01 ng per µg cytokine as determined by the LAL method.
Concentration
10 and 25 µg sizes are bottled at 200 µg/mL. 100 µg size and larger sizes are lot-specific and bottled at the concentration indicated on the vial (please contact technical support for concentration, or use our Lookup tool if you have a lot number.)
Please note, new lots of the 100 µg size will be lot-specific and may differ from previous lots that had a fixed concentration.
Storage & Handling
Unopened vial can be stored between 2°C and 8°C for up to 2 weeks, at -20°C for up to six months, or at -70°C or colder until the expiration date. For maximum results, quick spin vial prior to opening. The protein can be aliquoted and stored at -20°C or colder. Stock solutions can also be prepared at 50 - 100 µg/mL in appropriate sterile buffer, carrier protein such as 0.2 - 1% BSA or HSA can be added when preparing the stock solution. Aliquots can be stored between 2°C and 8°C for up to one week and stored at -20°C or colder for up to 3 months. Avoid repeated freeze/thaw cycles.
Activity
Bioactivity was measured by its property to chemoattract BaF3-mCCR3 transfectants in a dose dependent manner.
Application

Bioassay

Application Notes

BioLegend carrier-free recombinant proteins provided in liquid format are shipped on blue-ice. Our comparison testing data indicates that when handled and stored as recommended, the liquid format has equal or better stability and shelf-life compared to commercially available lyophilized proteins after reconstitution. Our liquid proteins are verified in-house to maintain activity after shipping on blue ice and are backed by our 100% satisfaction guarantee. If you have any concerns, contact us at tech@biolegend.com.

Distribution

CCL24 is expressed by epithelial cells, airway smooth muscle cells, and vascular endothelial cells. In addition, eotaxins are produced by cells isolated by bronchial alveolar lavage, including macrophages, monocytes, basophils, eosinophils, dendritic cells, and lymphocytes.

Function
CCL24 chemoattracts CCR3 bearing cells such as eosinophils, mast cells, basophils, and Th2 cells that play a role in allergic disorders. IL-4 and IL-13 induce CCL11 and CCL24 in esophagus and colonic epithelial cell, and IL-13 induces the production of CCL-24 in dendritic cells and alveolar macrophages. In addition, CCL24 is induced by IL-33 in lungs, and by IL-4 and LPS in monocytes and macrophages. The expression of CCL24 by alveolar epithelial cells requires histamine and its receptor H2R.
Interaction
Eosinophils, mast cells, Th2 lymphocytes, basophils, human dendritic cells, synovial tissue macrophages, lung epithelial cells, and airway smooth muscle cells.

Related FAQs

Does specific activity of a recombinant protein vary between lots?

Specific activity will vary for each lot and for the type of experiment that is done to validate it, but all passed lots will have activity within the established ED50 range for the product and we guarantee that our products will have lot-to-lot consistency. Please conduct an experiment-specific validation to find the optimal ED50 for your system.

Have your recombinants been tested for stability?

Our testing shows that the recombinant proteins are able to withstand room temperature for a week without losing activity. In addition the recombinant proteins were also found to withstand four cycles of freeze and thaw without losing activity.

How do you convert activity as an ED50 in ng/ml to a specific activity in Units/mg?
Use formula Specific activity (Units/mg) = 10e6/ ED50 (ng/mL)
How does the activity of your recombinant proteins compare to competitors?

We quality control each and every lot of recombinant protein. Not only do we check its bioactivity, but we also compare it against other commercially available recombinant proteins. We make sure each recombinant protein’s activity is at least as good as or better than the competition’s. In order to provide you with the best possible product, we ensure that our testing process is rigorous and thorough. If you’re curious and eager to make the switch to BioLegend recombinants, contact your sales representative today!

What is the specific activity or ED50 of my recombinant protein?

The specific activity range of the protein is indicated on the product datasheets. Because the exact activity values on a per unit basis can largely fluctuate depending on a number of factors, including the nature of the assay, cell density, age of cells/passage number, culture media used, and end user technique, the specific activity is best defined as a range and we guarantee the specific activity of all our lots will be within the range indicated on the datasheet. Please note this only applies to recombinants labeled for use in bioassays. ELISA standard recombinant proteins are not recommended for bioassay usage as they are not tested for these applications.
