Data Example

Intracellular Staining by Flow Cytometry View Larger

Detection of CCL18/PARC in Human Macrophages by Flow Cytometry. Macrophages were generated from positively selected (MAGH105) CD14+ human PBMC, cultured with 50 ng/ml rhM-CSF (216-MC), 10 ng/ml rhIL-10 (217-IL) and 10 ng/ml rhIL-4 (204-IL) for 6 days, then treated with 3nM Monensin overnight and stained with (A) Goat Anti-Human CCL18/PARC Biotinylated Polyclonal Antibody (Catalog # BAF394) or (B) control antibody (BAF108), followed by Allophycocyanin-conjugated Streptavidin (F0050) and Mouse anti-Human CD163 Alexa Fluor® 488-conjugated Monoclonal Antibody (FAB1607G). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (FC005). Staining was performed using our Staining Intracellular Molecules protocol.

Background: CCL18/PARC

CCL18, also known as alternative macrophage activation-associated CC chemokine (AMAC)-1, macrophage inflammatory protein (MIP)-4, and dendritic cell chemokine (DC-CK1), is a novel CC chemokine that is highly homologous to MIP-1 alpha (61% amino acid (aa) sequence identity). CCL18 cDNA encodes an 89 aa residue precursor protein with a 20 aa putative signal peptide that is cleaved to generate a 69 aa residue mature protein which lacks potential glycosylation sites. In vitro, CCL18 mRNA expression is induced in alternatively activated macrophages by Th2 cytokines such as IL-4, IL-10, and IL-13, and inhibited by IFN‑ gamma. CCL18 mRNA is also expressed by GM-CSF/IL-4-induced monocyte-derived dendritic cells. In vivo, CCL18 is highly expressed in lung and placenta but is not expressed in epidermal Langerhans cells. Recombinant CCL18 has been shown to chemoattract naive T cells but not monocytes or neutrophils.
