Our Abpromise guarantee covers the use of ab237924 in the following tested applications.

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

Application Abreviews Notes
IHC-P Use a concentration of 1 - 2 µg/ml.

Primary incubation for 30 minutes at room temperature.

Staining of formalin-fixed tissues requires boiling tissue sections in 10mM Citrate Buffer, pH 6.0, for 10-20 minutes followed by cooling at RT for 20 minutes.

Protein Array Use at an assay dependent concentration.


  • Relevance

    Mast cells contain a number of preformed chemical mediators such as histamine, chymase, carboxypeptidase and proteolytic tryptase. Human Mast Cell Tryptase is considered to be an important marker of mast cell activation as well as an important mediator of inflammation.
  • Cellular localization

    Secreted. Note: released from the secretory granules upon mast cell activation.

  • Formalin-fixed, paraffin-embedded human tonsil tissue stained for Mast Cell Tryptase using ab238072 at 2 μg/ml in immunohistochemical analysis.

    This data was produced with ab238072, the same antibody in a different formulation with BSA and Azide.

  • This data was produced with ab238072, the same antibody in a different formulation with BSA and Azide.
    ab238072 was tested in protein array against over 19000 different full-length human proteins.
    Z- and S- Score: The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.
    A MAb is specific to its intended target if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.
