CCL18

Natural and recombinant human CCL18/PARC

Expression system for standard: E.coli; Immunogen sequence: A21-A89

C-C motif chemokine 18

Secreted.

Expressed at high levels in lung, lymph nodes, placenta, bone marrow, dendritic cells present in germinal centers and T-cell areas of secondary lymphoid organs and macrophages derived from peripheral blood monocytes. Not expressed by peripheral blood monocytes and a monocyte-to-macrophage differentiation is a prerequisite for expression. Expressed in synovial fluids from patients with rheumatoid and septic arthritis and in ovarian carcinoma ascitic fluid.

Belongs to the intercrine beta (chemokine CC) family.
