CD203a antibody | PM18-7
Mouse anti Pig CD203a antibody, clone PM18-7 (MCA1973GA) used for the evaluation of CD203a expression on porcine leukocytes by flow cytometry.
Image caption:
Overview of flow cytometry analyses. (A) Gating strategy for identification of monocytes and macrophages. The peripheral blood is shown. Designation of population shown within each dot-plot is indicated above the dot-plot. Leukocytes were identified as viable (a) non-doublet (b) cells with typical light scatter properties of leukocytes (c). Then, macrophages were gated simply as CD203ahi leukocytes (d) and marked with blue color. Monocytes were gated as CD203alow/- SWC8-(e) CD172ahi(f) leukocytes where the CD203alow/- region was defined as the complementary region to the CD203ahi region. Then, SLA-DR+ monocytes were marked with red color and SLA-DR- monocytes were marked with green color (g). SLA-DR- region was defined as the complementary region to the SLA-DR+ region. Gating order is shown in the scheme (h). (B) Representative CD163 vs. CD14 dot-plots of macrophages (blue) and monocyte subpopulations (green: SLA-DR–, red: SLA-DR+) in various body compartments of control and APP-infected pigs.

Mouse anti Porcine CD203a antibody, clone PM18-7 (MCA1973GA) used to assess SWC9 expression on porcine dendritic cells following PRRSV infection by flow cytometry.
Image caption:
Single colour flow cytometry analysis of changes in several immunologically relevant cell surface molecules of bone marrow-derived dendritic cells after 48 h of incubation with different PRRSV strains at a multiplicity of infection of 0.01 (as determined by titration in porcine alveolar macrophages). Grey histograms show cells stained with an irrelevant isotype-matched antibody and a secondary FITC or phycoerythrin conjugated antibody. Blue histograms show uninfected cells and red line histograms correspond to PRRSV-infected cells. Averages and variation coefficients are included. Grey values show the uninfected cell parameters and black values correspond to PRRSV-infected cells. SwC3, SwC9, CD163, CD16.

Mouse anti Pig CD203a, clone PM18-7 recognizes porcine CD203a, originally clustered as SWC9 at the Second International Swine CD Workshop (Dominguez et al. 1998) and later identified as the porcine homologue of human ecto-nucleotidepyrophosphatase / phosphodiesterase 1 or ENPP1 (Petersen et al. 2007).
Mouse anti Pig CD203a was originally reported to immunoprecipitate two bands, one of ~;205 kDa and one of ~130 kDa (Dominguez et al. 1998) under both reducing and non-reducing conditions. Subsequent studies suggest that CD203a migrates as a homodimer of ~260 kDa under non-reducing conditions and a 130 kDa monomer under reducing conditions (Petersen et al. 2007) from preparations of porcine alveolar macrophages.
CD203a is expressed widely in macrophage populations with notably high levels on alveolar macrophages (Petersen et al. 2007, Hwang et al. 2015), it is not expressed on monocyte populations (McCullough et al. 1997, Hwang et al. 2015).
SWC1a, expressed at very much higher levels on monocytes than mature macrophages and CD203a (SWC9), expressed exclusively on mature tissue macrophages have been used as markers of monocyte-macrophage differentiation (Sanchez et al. 1999).
