Macrophages (HRP)

Recognizes porcine cells of the monocyte/macrophage lineage. Stains macrophages in a range of tissues, including the thymus, spleen periarteriolar lymphoid sheath (PALS), spleen red pulp and the Peyer's patches. Expression has also been reported on some non-heamatopoietic cells including endothelial cells. Expression of the antigen is increased with maturation, with higher expression on peritoneal and alveolar macrophages. Some expression has also been observed on peripheral blood lymphocytes. Recognizes a 105kD antigen in pig macrophages.
