Target data
Function
Abundant protease in the cytosolic granules of cytotoxic T-cells and NK-cells which activates caspase-independent pyroptosis when delivered into the target cell through the immunological synapse (PubMed:3262682, PubMed:3263427, PubMed:1985927). It cleaves after Asp (PubMed:8258716, PubMed:1985927). Once delivered into the target cell, acts by catalyzing cleavage of gasdermin-E (GSDME), releasing the pore-forming moiety of GSDME, thereby triggering pyroptosis and target cell death (PubMed:32188940, PubMed:31953257). 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 (PubMed:9852092).

Notes
ab219803 is the carrier-free version of Anti-Granzyme B antibody [EPR20129-217] ab208586.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
Supplementary info

- Activity summary
Granzyme B also known as GZMB GB11 or granzyme B protein is a serine protease with a molecular mass of approximately 32 kDa. It is expressed mainly in cytotoxic T lymphocytes and natural killer (NK) cells. This enzyme plays a mechanical role in inducing apoptosis in target cells serving as an effector protein in the immune system's defense against virally infected cells or transformed cancer cells. The activity of granzyme B relies on its ability to cleave after aspartate residues in substrate proteins leading to the activation of apoptotic pathways.
- Biological function summary
Granzyme B participates prominently in the immune response by activating caspases particularly caspase-3 which promotes the breakdown of cellular components necessary for apoptosis. Granzyme B does not function in isolation but acts in concert with other immune system factors such as perforin to effectively induce cell death. Perforin creates pores in the target cell membrane allowing granzyme B to enter and instigate the apoptosis sequence. The enzyme also contributes to the processing of cytokines which enhances the immune response further.
- Pathways
Studies have determined that granzyme B is critical in the apoptosis pathway particularly in the granule exocytosis pathway. It closely interacts with proteins such as perforin and other granzymes to mediate apoptosis in target cells. Granzyme B also plays a role in the inflammatory response and can influence pathways associated with cytotoxic T cell signaling. Its pathway interactions ensure effective elimination of damaged or infected cells maintaining tissue homeostasis.
- Associated diseases and disorders
Granzyme B has associations with autoimmune diseases and cancer. Abnormally high levels of granzyme B can contribute to tissue damage and inflammation in autoimmune conditions like rheumatoid arthritis. In the context of cancer granzyme B aids in tumor surveillance and destruction when functioning correctly but impaired granzyme B activity can lead to evasion of immune detection by cancerous cells. Perforin also plays a role in these conditions closely working with granzyme B to either protect against or drive disease progression.

Tissue Microarrays stained for "Anti-Granzyme B antibody [EPR20129-217]" using "Anti-Granzyme B antibody [EPR20129-217] ab208586"in immunohistochemical analysis. This table provides a detailed overview of positive (tick mark) and negative (cross mark) staining per sample type tested. The sections were pre-treated using Heat mediated antigen retrieval using Bond™ Epitope Retrieval Solution 2 (pH 9.0) for 20 minutes. The sections were incubated with Anti-Granzyme B antibody [EPR20129-217] ab208586 for 30 mins at room temperature followed by a ready to use Rabbit specific IHC polymer detection kit HRP/DAB (Rabbit specific IHC polymer detection kit HRP/DAB ab209101). The immunostaining was performed on a Leica Biosystems BOND® RX instrument.

Fluorescence multiplex immunohistochemical analysis of Human breast cancer tissue (formalin-fixed paraffin-embedded section).
Merged staining of Anti-PD-L1 (Anti-PD-L1 antibody [CAL10] - BSA and Azide free ab251611; cyan; Opal™ 520), Anti-Granzyme B (ab219803; yellow; Opal™ 540), Anti-PD1 (Anti-PD1 antibody [CAL20] - BSA and Azide free ab251613; magenta; Opal™ 570), Anti-pan Cytokeratin (Anti-pan Cytokeratin antibody [C-11] - BSA and Azide free ab264485; red; Opal™ 620), Anti-EpCAM (Anti-EpCAM antibody [EPR20532-225] - BSA and Azide free ab225894; red; Opal™ 620), Anti-CD8 alpha (Anti-CD8 alpha antibody [CAL66] - BSA and Azide free ab251596; green; Opal™ 650) and Anti-FOXP3 (Anti-FOXP3 antibody [236A/E7] - BSA and Azide free ab96048; orange; Opal™ 690). EpCAM and pan-cytokeratin share the same dye and color. Dyes are pseudo-colored for better contrast of the markers.
The immunostaining was performed on a Leica Biosystems BOND® MAX instrument with an Opal™ 6-Plex Detection Kit (NEL821001KT, Akoya Biosciences®).
The section was incubated in six rounds of staining; sequentially for Anti-PD-L1 antibody [CAL10] - BSA and Azide free ab251611 (1/750 dilution), ab219803 (1/250 dilution), Anti-PD1 antibody [CAL20] - BSA and Azide free ab251613 (1/750 dilution), Anti-pan Cytokeratin antibody [C-11] - BSA and Azide free ab264485 (0.5 μg/ml), Anti-EpCAM antibody [EPR20532-225] - BSA and Azide free ab225894 (1/1250 dilution), Anti-CD8 alpha antibody [CAL66] - BSA and Azide free ab251596 (1/1500 dilution) and Anti-FOXP3 antibody [236A/E7] - BSA and Azide free ab96048 (10 μg/ml); each using a separate fluorescent tyramide signal amplification system. EDTA based antigen retrieval (Leica Biosystems BOND® Epitope Retrieval Solution 2, pH 9.0, 20 minutes) was used in between rounds of tyramide signal amplification to remove the antibody from the previous round, to avoid any cross-reactivity. DAPI (dark blue) was used as a nuclear counter stain.
Microscopy and pseudocoloring of individual Opal™ dyes was performed using a Vectra 3 Imaging System (Akoya Biosciences®).This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (Anti-Granzyme B antibody [EPR20129-217] ab208586).
