Macrophage Marker (S100A8/A9); Clone S100/722 (Concentrate)
Immunogen: Recombinant human S100 protein
Isotype: IgG1, kappa
Species Reactivity: Human, Baboon, Monkey, Cow, Pig, Goat, Horse, Cat, Dog, Rabbit, Guinea pig, Rat, and Mouse. Others not known.
Positive Control: Tonsil, lymph node, or spleen.
Specificity: Recognizes a 12-14kDa subunit of S100A8/A9 (also known as Calgranulin A/B or MRP-8/14); expressed by granulocytes, monocytes, and tissue macrophages. This antibody reacts with neutrophils, monocytes, macrophages, and squamous mucosal epithelia, and has been shown to be an important marker for identifying macrophages in tissue sections.
