Granzyme B Rabbit Polyclonal Antibody

Fluorescence multiplex immunohistochemical analysis of human tonsil (Formalin/PFA-fixed paraffin-embedded sections). Panel A: the merged image of anti-CD14 (ET1610-85, Green), anti-CD21 (HA721163, Red) and anti-Granzyme B (HA500252, Yellow) on tonsil. HRP Conjugated UltraPolymer Goat Polyclonal Antibody HA1119/HA1120 was used as a secondary antibody. The immunostaining was performed with the Sequential Immuno-staining Kit (IRISKit™MH010101, www.luminiris.cn). The section was incubated in three rounds of staining: in the order of ET1610-85 (1/800 dilution), HA721163 (1/1,000 dilution) and HA500252 (1/200 dilution) for 20 mins at room temperature. Each round was followed by a separate fluorescent tyramide signal amplification system. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 30 mins at 95℃. DAPI (blue) was used as a nuclear counter stain. Image acquisition was performed with Zeiss Observer 7 Inverted Fluorescence Microscope.

Fluorescence multiplex immunohistochemical analysis of tertiary lymphoid structures in human cervical cancer (Formalin/PFA-fixed paraffin-embedded sections). Panel A: the merged image of anti-Granzyme B (HA500252, magenta), anti-CD4 (ET1609-52, yellow) on tertiary lymphoid structures. Panel B: anti- Granzyme B stained on cytotoxic NK cells and dendritic cells. Panel C: anti-CD4 stained on helper T cells and Treg cells. HRP Conjugated UltraPolymer Goat Polyclonal Antibody HA1119/HA1120 was used as a secondary antibody. The immunostaining was performed with the Sequential Immuno-staining Kit (IRISKit™MH010101, www.luminiris.cn).

Immunohistochemical analysis of paraffin-embedded human liver tissue with Rabbit anti-Granzyme B antibody (HA500252) at 1/3,000 dilution.

The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH₂O and PBS, and then probed with the primary antibody (HA500252) at 1/3,000 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
