By immunohistochemistry, it specifically recognizes a protein in melanocytes and melanomas. This MAb reacts with junctional and blue nevus cells and variably with fetal and neonatal melanocytes. Intradermal nevi, normal adult melanocytes, and non-melanocytic cells are negative. It does not stain tumor cells of epithelial, lymphoid, glial, or mesenchymal origin.This Mab labels formalin-fixed, paraffin-embedded melanomas and other tumors showing melanocytic differentiation.
Applications
Suitable for use in Immunofluorescence, Flow Cytometry, FLISA, Immunohistochemistry. Other applications not tested.
Recommended Dilution
Flow Cytometry: 0.5-1ug/million cells Immunofluorescence: 1-2ug/ml Immunohistochemistry (Frozen & Formalin-fixed): 1-2ug/ml for 30 minutes at RT (Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes) Optimal dilution for a specific application should be determined.
Positive Control
SK-MEL-28 cells or Melanoma
