Description: This antibody labels human mast cells and is a useful tool for the recognition of very atypical or immature mast cells (MC) in mast cell leukaemia, and for the detection of small, even minute, dense focal MC infiltrates in staging procedures in patients with known cutaneous mastocytosis.
