Amino Acid Sequence: AQVGTNKELCCLVYTSWQIPQKFIVDYSETSPQCPKPGVILLTKRGRQICADPNKKWVQKYISDLKLNA
Background: CCL18, also designated dendritic cell (DC)3-derived CC chemokine 1, pulmonary and activation-regulated chemokine, alternative macrophage activation-associated CC chemokine 1, and MIP-4, is a human chemokine structurally related to CCL3. CCL18 was shown to be expressed in germinal centers of tonsils by dendritic cells and to attract mainly naive T cells, CD38–, mantle zone B lymphocytes and DC. The production of CCL18 by APC is enhanced by Th2 cytokines like IL-4 and IL-13 and suppressed by IFN-gamma.
Biological Activity: Determined by its ability to chemoattract human T cells using a concentration range of 2.0-40.0 ng/ml.
Description: Recombinant CCL18 is a disulfide-linked homodimeric protein consisting of 70 amino acid residues and migrates as an approximately 16 kDa protein under non-reducing conditions and 8 kDa under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human MIP-4 mature chain was expressed in E. coli.
Endotoxin Level: <0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Format: lyophilized protein
Formulation: Lyophilized from a 0.2 µm filtered 20 mM Phosphate buffer, 100 mM NaCl, pH 7.5.
Genbank: P55774
Purity: ≥98% by SDS-PAGE and HPLC
Reconstitution: Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage Stability: The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
Uniprot: P55774
Warnings: Avoid freeze/thaw cycles.
Biosafety Level: Not applicable (BSL-1)
