Application Abreviews Notes
Flow Cyt
  • Application notes
    Flow Cyt: 1/10 - 1/100. Membrane permeabilization is required for flow cytometry. The use of LeucopermTM is recommended for this purpose. Use 10µl of the suggested working dilution to label 106 cells or 100ul whole blood.
    IHC-Fr: Use at an assay dependent dilution. Hsi, B-L. et al. (1986)
    IP: Use at an assay dependent dilution.

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function

      This enzyme is necessary for target cell lysis in cell-mediated immune responses. It cleaves after Asp. Seems to be linked to an activation cascade of caspases (aspartate-specific cysteine proteases) responsible for apoptosis execution. Cleaves caspase-3, -7, -9 and 10 to give rise to active enzymes mediating apoptosis.
    • Sequence similarities

      Belongs to the peptidase S1 family. Granzyme subfamily.
      Contains 1 peptidase S1 domain.
    • Cellular localization

      Cytoplasmic granule. Cytoplasmic granules of cytolytic T-lymphocytes and natural killer cells.

    Customer reviews and Q&As


    Thank you for contacting Abcam.

    The main difference between ab103157, Granzyme B antibody [CLB-GB11] (FITC) and ab10912, -Granzyme B antibody [ GB11 ] is that ab103157 is conjugated to a FITC tag, whereas ab10912 is unconjugated. Also although we don not know the exact epitope sites, it is likely that they recognize different regions of the protein.

    If there is anything else I can help you with, please let me know.
