  • 描述
    小鼠单克隆抗体[CC1] to Mast Cell Chymase
  • 宿主
  • 特异性
    Ab2377 recognises recombinant human mast cell chymase. However, endogenous protein is not detected in WB due to low expression, therefore we do not guarantee this antibody in WB.

  • 免疫原

    Purified human skin Chymase.

  • 阳性对照
    • Tonsil. IHC-P: FFPE human tonsil tissue sections.
  • 常规说明

    This antibody clone is manufactured by Abcam.

    If you require this antibody in a particular buffer formulation or a particular conjugate for your experiments, please contact or you can find further information here.

    Mast cells contain a number of preformed chemicals mediators such as histamine, chymase, carboxypeptidase and proteolytic tryptase. Human Mast Cell Chymase is considered to be an important marker of mast cells as well as an important mediator of inflammation.



Our Abpromise guarantee covers the use of ab2377 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
IHC-P Use a concentration of 0.2 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
IHC-Fr Use at an assay dependent concentration. 1/100-1/200 in an ABC method.
Flow Cyt Use 1-2µg for 106 cells.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.


  • 应用说明

    • IHC image of Mast Cell Chymase staining in human tonsil formalin fixed paraffin embedded tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2377, 0.2µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.


      For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
