    IHC staining of purified anti-Granzyme B antibody (clone M3304B06) on formalin-fixed paraffin-embedded human tonsil tissue. Following antigen retrieval using Tris-EDTA buffer (10mM Tris, 1mM EDTA, pH 9.0), the tissue was incubated with 5.0 µg/mL of the primary antibody overnight at 4&Deg;C, followed by incubation with Alexa Fluor® 647 goat anti-mouse IgG (magenta) (Cat. No. 405322) for one hour at room temperature. Nuclei were counterstained with DAPI (blue) (Cat. No. 422801), and the slides were mounted with ProLong™ Gold Antifade Mountant. Scale bar: 50 µm.

Granzyme B is a serine protease that is mainly produced by cytotoxic T cells (CTL) and NK cells. It plays important roles in cytotoxic lymphocyte-mediated apoptosis, chronic inflammation, and impaired wound healing. Granzyme B is packaged in cytoplasmic granules that are exocytosed towards a bound target cell, and subsequently activates multiple protein substrates to induce apoptosis. Perforin facilitates the transfer of Granzyme B into the target cell. Most circulating CD56+ CD8- NK cells and approximately half of circulating CD8+ T cells coexpress both Granzyme A and B. The activation of CD8+ and CD4+ T lymphocytes induces substantial expression of Granzyme B, but not Granzyme A. Recently, Granzyme B has been found to be produced by other cell types such as CD34+ hematopoietic progenitor cells, keratinocytes, basophils, mast cells, plasmacytoid dendritic cells, B cells, and smooth muscle cells. Elevated levels of Granzyme B are also found in some kinds of autoimmune diseases, type 1 diabetes, and cardiovascular diseases.

Recommended Usage

Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.5 - 2.0 µg per mL. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 1.0 - 10 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Cytotoxic T cells, NK cells, and neutrophils.

Granzyme B is able to induce target cell apoptosis by activating caspase independent pathways. Granzyme B is induced in CD8+ T lymphocytes with ConA / IL-2 and CD4+ T lymphocytes with anti-CD3/CD28 or anti-CD3/CD46.
