Na channel β1 subunit antibody | knockout validation | Cell Signaling 13950

This is a knockout-validated antibody summary, based on the publication "β1-C121W Is Down But Not Out: Epilepsy-Associated Scn1b-C121W Results in a Deleterious Gain-of-Function", as cited below [1]. Labome curates formal publications to compile a list of antibodies with unambiguous specificity within Validated Antibody Database (VAD).

Antibody information

Rabbit monoclonal IgG

Company: Cell Signaling

Antibody: Na Channel β1 Subunit

Catalog number: 13950

Summary: Rabbit monoclonal IgG against a synthetic peptide corresponding to residues surrounding Ala51 of human sodium channel β1 subunit protein. Reacts with human, mouse and rat. Suitable for western blot and immunoprecipitation.

Validation Method

Western blot

Sample

Mouse brain membrane extracts from WT and Scn1b−/− mice. Complete protease inhibitors (Roche Diagnostics) were added to all solutions at twice the recommended concentration to minimize protein degradation. Brains were dissected and homogenized in ice-cold Tris-EGTA (50 mm Tris, 10 mm EGTA, pH 8.0).

Blocking agent

5% nonfat dry milk and 1% bovine serum albumin in TBST (0.1 m Tris-Cl, 0.5 m NaCl, pH 7.5, 0.1% Triton X-100).

Primary incubation

1:3,000 dilution overnight at 4°C.

Secondary incubation

1:500 dilution HRP-conjugated goat anti-rabbit (Thermo Fisher Scientific) for 1 h at room temperature.

Detection

West Femto or West Dura reagent (Thermo Fisher Scientific, catalog #34095 or 34076) was used for detection. Immunoreactive signals were recorded using a Leica Odyssey Fc Imager.

Notes

The article lists the correct clone number (but wrong catalog number) to indicate the antibody (from the author's feedback).
