Macrophage Marker (Macrophage L1 Protein) (Calprotectin); Clone MAC387 (Concentrate)
Immunogen: Affinity purified monocyte membrane preparation
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: This antibody recognizes the L1 or Calprotectin molecule, an intra-cytoplasmic antigen comprised of 12-14kDa subunits 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.
