General description
Macrophage-derived chemokine (MDC) is also known as C-C motif chemokine ligand 22 (CCL22). It is a CC chemokine that is produced in B cells, macrophages, monocyte-derived dendritic cells, activated natural killer (NK) cells and cluster of differentiation 4 (CD4) T cells. The gene encoding it is localized on human chromosome 16. Recombinant human MDC is an 8.0kDa protein containing 67 amino acid residues including the four highly conserved cysteine residues present in the CC chemokines.
Biochem/physiol Actions
Macrophage-derived chemokine (MDC) signals through the C-C chemokine receptor type 4 (CCR4). It chemo-attracts monocytes, dendritic cells and natural killer (NK) cells and aids in their function. The protein exerts human immunodeficiency virus (HIV) suppressive activity. The 67 amino acid form of MDC displays reduced chemoattractant activity but retains HIV suppressive activity. It is expressed in various cancers and is involved in recruitment of regulatory T cells (Treg) within a tumor.
Physical form
Lyophilized with no additives.
Preparation Note
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
