Tested Applications

• Positive WB detected in: NK-92 cells, U-937 cells
• Positive IHC detected in: human lymphoma tissue, human tonsillitis tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive FC (Intra) detected in: NK-92 cells

Recommended dilution

• Western Blot (WB): WB : 1:2000-1:16000
• Immunohistochemistry (IHC): IHC : 1:500-1:2000
• Flow Cytometry (FC) (INTRA): FC (INTRA) : 0.25 ug per 10^6 cells in a 100 µl suspension

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

GZMB(Granzyme B) is also named as CGL1, CSPB, CTLA1, GRB and belongs to the Granzyme subfamily. This enzyme is necessary for target cell lysis in cell-mediated immune responses. The cytotoxic lymphocyte protease granzyme B (GzmB) can promote apoptosis through direct processing and activation of members of the caspase family. GzmB can also cleave the BH3-only protein, BID, to promote caspase-independent mitochondrial permeabilization (PMID:17283187). GzmB induces laminB degradation in isolated nuclei less efficiently than GzmA (PMID:11331782). This full length protein has 2 glycosylation sites and a signal peptide. Unglycosylated human granzyme B is 26 kDa and high mannose glycosylated is 32 kDa and only 32kDa or smaller forms of granzyme B are accumulated within nuclei (PMID:8626751). GzmB also forms dimers.
