Human MIP4 (CCL18) Recombinant
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 inE. coli.

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.
UniProt
P55774
Endotoxin
< 0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Purity
≥ 98% by SDS-PAGE and HPLC
Format
Lyophilized protein
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.
Shipping Conditions
Gel Packs or Dry Ice
Storage Conditions
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.
Calculated Molecular Weight
8 kDa
Formulation
Lyophilized from a 0.2 µm filtered 20 mM Phosphate buffer, 100 mM NaCl, pH 7.5.
