All MDC reagents are produced in house and quality controlled, including 1 MDC Antibody, 26 MDC Gene, 2 MDC Protein, 1 MDC qPCR. All MDC reagents are ready to use.
Recombinant MDC proteins are expressed by E. coli with fusion tags as N-His.
MDC antibodies are validated with different applications, which are ELISA.
MDC cDNA clones are full length sequence confirmed and expression validated. There are 13 kinds of tags for each MDC of different species, especially GFP tag, OFP tag, FLAG tag and so on. There are three kinds of vectors for choice, cloning vector, expression vector and lentivrial expression vector.
Chemokine (C-C motif) ligand 22(ABCD-1 / CCL22)is a kind of CC chemokine which is a family of secreted proteins involved in immunoregulatory and inflammatory processes. The cytokine displays chemotactic activity for monocytes, dendritic cells, natural killer cells and for chronically activated T lymphocytes. It also displays a mild activity for primary activated T lymphocytes and has no chemoattractant activity for neutrophils, eosinophils and resting T lymphocytes. This ABCD-1 / CCL22 chemokine binds to chemokine receptor CCR4. This chemokine may play a role in the trafficking of activated / effector T lymphocytes to inflammatory sites and other aspects of activated T-lymphocyte physiology. ABCD-1 / CCL22 is highly expressed in macrophage and in monocyte-derived dendritic cells, and thymus, and in Langerhans' cell histiocytosis and atopic dermatitis but not in dermatopathic lymphadenopathy. This chemokine is also found in lymph node, appendix, activated monocytes, resting and activated macrophages. This protein is lower expressed in lung and spleen and very weekly expressed in small intestine.
