NF-kappaB p105/p50 (Phospho-S337) Antibody

Western blot analysis of NF-kappaB p105/p50 (Phospho-S337) expression in Hela-TNFa-30 min (A), Hela-TNFa-5min (B), Hela (C) whole cell lysates. (Predicted band size: 105 kD; Observed band size: 105; 50 kD)

Immunohistochemical analysis of NF-kappaB p105/p50 (Phospho-S337) staining in human prostate cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (Phospho-H 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Immunofluorescent analysis of NF-kappaB p105/p50 (Phospho-S337) staining in MCF7 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a hidified chamber. Cells were washed with PBST and incubated with a DyLight 594-conjugated secondary antibody (red) in PBS at room temperature in the dark.

Direct ELISA antibody dose-response curve using Anti-NF-kappaB p105/p50 (Phospho-S337) Antibody. Antigen (Phosphopeptide and non-phosphopeptide) concentration is 5 ug/ml. Goat Anti-Rabbit IgG (H&L) - HRP was used as the secondary antibody, and signal was developed by TMB substrate.
