Description：Recombinant Human CCL18 Protein is produced by E. coli expression system and the target gene encoding Ala21-Ala89 is expressed with a 6His tag at the N-terminus.Form：Lyophilized from a 0.2 μM filtered solution of 20mM PB, 150mM NaCl, pH 7.4.Gene Symbol：CCL18Alternative Names：AMAC1; DCCK1; MIP4; PARC; SCYA18; C-C motif chemokine 18; Alternative macrophage activation-associated CC chemokine 1; AMAC-1; CC chemokine PARC; Dendritic cell chemokine 1; DC-CK1; Macrophage inflammatory protein 4; MIP-4; Pulmonary and activation-regulated chemokine; Small-inducible cytokine A18 Entrez Gene (Human)： 6362; SwissProt (Human)： P55774; Purity：Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure：MGSSHHHHHH SSGLVPRGSH MAQVGTNKEL CCLVYTSWQI PQKFIVDYSE TSPQCPKPGV ILLTKRGRQI CADPNKKWVQ KYISDLKLNADirections for Use：Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control：Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability：Lyophilized protein should be stored at -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 2-8°C for 2-7 days. Aliquots of reconstituted samples are stable at -20°C for 3 months.
