Anti-TNF alpha Antibody

IHC analysis of TNF alpha using anti-TNF alpha antibody (PA1079).
TNF alpha was detected in a paraffin-embedded section of human B lymphocytic tumor tissue. Heat mediated antigen retrieval was performed in EDTA buffer (pH 8.0, epitope retrieval solution). The tissue section was blocked with 10% goat serum. The tissue section was then incubated with 2 μg/ml rabbit anti-TNF alpha Antibody (PA1079) overnight at 4°C. Peroxidase Conjugated Goat Anti-rabbit IgG was used as secondary antibody and incubated for 30 minutes at 37°C. The tissue section was developed using HRP Conjugated Rabbit IgG Super Vision Assay Kit (Catalog # SV0002) with DAB as the chromogen.

Flow Cytometry analysis of CACO-2 cells using anti-TNF alpha antibody (PA1079).
Overlay histogram showing CACO-2 cells stained with PA1079 (Blue line). The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-TNF alpha Antibody (PA1079, 1 μg/1x10⁶ cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (BA1127, 5-10 μg/1x10⁶ cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/1x10⁶) used under the same conditions. Unlabelled sample (Red line) was also used as a control.
