Measured by its ability to neutralize CCL22/MDC-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR4. The Neutralization Dose (ND50) is typically 0.3-1.0 µg/mL in the presence of 15 ng/mL Recombinant Mouse CCL22/MDC.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Chemotaxis Induced by CCL22/MDC and Neutralization by Mouse CCL22/MDC Antibody. Recombinant Mouse CCL22/MDC (Catalog # 439‑MD) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR4 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin. Chemotaxis elicited by Recombinant Mouse CCL22/MDC (15 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse CCL22/MDC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF439). The ND50 is typically 0.3-1.0 µg/mL.

Mouse ABCD-1, the mouse orthologue of the human macrophage-derived chemokine (MDC)/stimulated T cell chemotactic protein (STCP-1), is a CC chemokine cloned from activated mouse B cells. Mouse MDC cDNA encodes a precursor protein of 92 amino acid (aa) residues with a 24 aa residue predicted signal peptide that is cleaved to yield a 68 aa residue mature 7.8 kDa protein. At the amino acid sequence level, mouse and human MDC share 64% identity and 83% similarity. The genomic organization of the mouse and human MDC genes are very similar, exhibiting sequence identity at the intron-exon boundaries. Mouse MDC is expressed at high levels in dendritic cells and activated B lymphocytes. Low levels of mouse MDC mRNA are also detectable in lung, unstimulated spleen cells, lymph node cells and in thymocytes. MDC is a functional ligand for the CC chemokine receptor 4. Recombinant or chemically synthesized mature mouse MDC has been shown to induce chemotaxis or Ca2+ mobilization in activated mouse and human T cells.
