MDC Recombinant Protein

MDC is a CC chemokine that is produced in B cells, macrophages, monocyte-derived dendritic cells, activated NK cells and CD4 T cells. It signals through the CCR4 receptor. MDC chemoattracts monocytes, dendritic cells and NK cells and exerts HIV suppressive activity. The 67 amino acid form of MDC displays reduced chemoattractant activity but retains HIV suppressive activity. Recombinant human MDC is an 8.0 kDa protein containing 67 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines.

The lyophilized MDC recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted MDC is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing MDC recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
