DescriptionMouse monoclonal [CC1] to Mast Cell Chymase
SpecificityAb2377 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.
Tested applicationsSuitable for: IHC-P, IHC-Fr, Flow Cytmore details
Unsuitable for: WB
Species reactivityReacts with: Rat, Human, Pig
corresponding to Mast Cell Chymase.
- Tonsil. IHC-P: FFPE human tonsil tissue sections.
This antibody clone is manufactured by Abcam.
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.
|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.

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.
