CD203a antibody | PM18-7
Filter by Application:F IF Reset
|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. 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).
