Filter:
  • Western Blot (WB) analysis of HeLa cells using Mesothelin Monoclonal antibody (66404-1-Ig)

    WB analysis of HeLa using 66404-1-Ig (same clone as 66404-1-PBS)

    HeLa cells were subjected to SDS PAGE followed by western blot with 66404-1-Ig (Mesothelin antibody) at dilution of 1:1000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66404-1-PBS in a different storage buffer formulation.

  • Western Blot (WB) analysis of various lysates using Mesothelin Monoclonal antibody (66404-1-Ig)

    WB analysis using 66404-1-Ig (same clone as 66404-1-PBS)

    Various lysates were subjected to SDS PAGE followed by western blot with 66404-1-Ig (Mesothelin antibody) at dilution of 1:5000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 66404-1-PBS in a different storage buffer formulation.

  • Immunohistochemistry (IHC) staining of human ovary tumor tissue using Mesothelin Monoclonal antibody (66404-1-Ig)

    IHC staining of human ovary tumor using 66404-1-Ig (same clone as 66404-1-PBS)

    Immunohistochemical analysis of paraffin-embedded human ovary tumor tissue slide using 66404-1-Ig (Mesothelin antibody) at dilution of 1:200 (under 10x lens. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0). This data was developed using the same antibody clone with 66404-1-PBS in a different storage buffer formulation.

Background Information

Mesothelin (MSLN) is a 40kDa GPI-anchored surface glycoprotein that is expressed on pleural and peritoneal mesothelial cells, but not in other non-neoplastic tissues. The mesothelin gene encodes a 69-71kDa precursor protein that is processed to a 40kDa membrane-bound protein termed mesothelin and a 31kDa shed fragment called megakaryocyte-potentiating factor (MPF) that is released from the cell. Mesothelin is a tumor differentiation antigen present at low levels on a restricted set of normal adult tissues (e.g. mesothelium), and is expressed at high levels in mesotheliomas, as well as ovarian, pancreatic, and lung cancers. Mesothelin may be a new target for immunotherapy (PMID: 20922056, 18691948, 15217923).
