Merck, MAB16985-25UG, Anti-MCAM Antibody, clone P1H12

General description
MUC18 antigen (CD146), a member of the immuoglobulin superfamily, is an intrinsic membrane glycoprotein of 110-120 kDa found on the surface of endothelial cells, bone marrow fibroblasts and various melanomas. MUC18 has been used as a marker of tumor progression in human melanoma because expression in those tumors correlates strongly with poor prognosis and the development of metastic disease. In addition, a number of human T, B and myeloid leukemic cell lines seem to express MUC18. The close structural relationship with N-CAM and related molecules suggests that MUC18 may be also a developmentally regulated cell adhesion molecule (Melanoma adhesion molecule or MCAM).
110 kDa
Immunogen
Immunization of mice with HUVEC.
Application
Anti-MCAM Antibody, clone P1H12 detects level of MCAM & has been published & validated for use in ELISA, FC, IC, IH, IP & WB.
Immunocytochemistry:
1-10 μg/mL of a previous lot worked in immunocytochemistry.Works best on EDTA or Trypsin lifted endothelial cells.

Immunohistochemistry:
1-10 µg/mL. 4% PFA for 30min RT or <2hrs at 4°C. Block w/ 1%BSA/0.2% tween20/PBS for 30min. Works well in frozen tissue; fixed or unfixed.
