Granzyme B antibody | GB11
Granzyme B plays a key role in the induction of apoptosis by CTLs. After delivery to the target cell, Granzyme B activates the cascade of caspases that finally results in cell death.
Mouse anti Granzyme B antibody, clone GB11 is suitable for the detection of Granzyme B expressing cells by flow cytometry. In normal peripheral blood approximately 20% of CD8+ve T cells have been found to express Granzyme B.

Applications of Granzyme B antibody
|Application Name||Verified||Min Dilution||Max Dilution|
|Flow Cytometry 1||1/10||1/100|
|Immunohistology - Frozen|
- 1 Membrane permeabilisation is required for this application. Bio-Rad recommends the use of Leucoperm™ (Product Code BUF09) for this purpose.
- Flow Cytometry
- Use 10ul of the suggested working dilution to label 106 cells or 100ul whole blood.
- This antibody has been reported to function as a capture reagent in sandwich ELISA assays for soluble Granzyme B in conjunction with biotin conjugated GB10 as detection reagent.
