Rabbit monoclonal IgG

Company: Cell Signaling

Antibody: DR4

Catalog number: 42533

Summary: Rabbit monoclonal IgG against a recombinant protein specific to the carboxy terminal, cytoplasmic domain of human DR4 protein. Reacts with human by western blot, immunoprecipitation, immunofluorescence/immunocytochemistry and flow cytometry..

Western blot

WT and DR4- and DR4/DR5 knockout HeLa cells. Cells were lysed in radioimmunoprecipitation assay (RIPA) buffer (Thermo Scientific) supplemented with protease inhibitors (Roche) and phosphatase inhibitors (Roche).

5% nonfat dry milk in Tween–Tris-buffered saline (TBS) (TTBS) for 1 h at room temperature.

1:1,000 dilution in blocking solution for 1 to 2 h at room temperature or overnight at 4°C with agitation.

1:5,000 dilution HRP-conjugated anti-rabbit (Zymax) in blocking buffer for 1 h at room temperature.

Enhanced chemiluminescence (ECL) reaction using a freshly prepared ECL reagent (Promega).
