Application

This Anti-Potassium Channel Kv3.1b Antibody is validated for use in IH, IP, WB for the detection of Potassium Channel Kv3.1b.
Western blot: 1:200 using ECL on rat brain membranes.

Immunohistochemistry on rat brain sections.

Immunoprecipitation

Dilutions should be made using a carrier protein such as BSA (1-3%)

Optimal working dilutions must be determined by the end user.

PROTOCOL FOR IMMUNOHISTOCHEMISTRY

Sacrifice and tissue processing:

Rats are deeply anesthetized with pentobarbital sodium (Pental). Brain is fixed by transcardial perfusion, first with 50 mL of phosphate buffered saline (0.02M PBS, pH 7.4) containing heparin (5U/ml), then with 220 mL of ice-cold 4% paraformaldehyde in 0.1M PBS, pH 7.5 containing sucrose 4%. Brain is cut in coronal blocks and further fixed by immersion in the same fixative, refrigerated, for 1-2 hours. Brain blocks are transferred to 10% sucrose in 0.1M PBS and sectioned in a cryostat within 3 days. Brain sections, 30 μm thick, are floated in 0.1M PBS and then preserved in a cryopreservation buffer at -20°C. The cryopreservation buffer contains 40% ethylene glycol and 1% polyvinylpyrrolidone in 0.1M potassium acetate buffer, pH 6.5.

Staining procedure:

1. Floating sections are rinsed in 0.02M PBS, 2x 5 minutes.

2. Endogenous peroxidase activity is quenched by incubation with 0.2 % hydrogen peroxide in 0.1M phosphate buffer pH 7.3 containing 0.2% Triton X-100 for 25 minutes at room temperature.

3. Sections are rinsed in 0.02M PBS, 2x 5 minutes.

4. Sections are incubated with the primary antiserum in a medium containing 0.3% Triton X-100, 0.05% Tween 20, 4% normal donkey serum (NDS), for 1 hour at room temperature and then overnight refrigerated.

5. Sections are rinsed in 0.02M PBS, containing 4% NDS, 2x 5 minutes.

Sections are incubated with biotinylated donkey anti-rabbit (from Chemicon USA, catalog number AP182B) diluted 1:400 in 0.02M PBS, containing 0.3% Triton X-100, 0.05% Tween 20, and 4% NDS, for 1 hour at room temperature and then overnight refrigerated.

1. Sections are rinsed in 0.02M PBS containing 4% NDS, 2x 5 min.

2. Sections are incubated with extravidin-peroxidase (Sigma Catalog number E2886) diluted 1:100 in 0.02M PBS, for 45 minutes at room temperature.

3. Sections are rinsed in 0.02M PBS, 3x 5 minutes.

Color development:

1. Sections are incubated with a solution of diaminobenzidine at the concentration of 0.0125% and containing 0.05% nickel ammonium sulfate for 10 minutes at room temperature.

2. Sections are transferred to the same DAB solution but with added hydrogen peroxide at a final concentration of 0.0015%. Duration of incubation should be adjusted by the end user.

3. Sections are rinsed in 0.02M PBS, 4x 10 minutes.

4. Sections are mounted on glass slides (gelatinized or coated by any other type of adhesive material) and allowed to dry.

5. Sections are dehydrated in ascending series of ethanol concentrations (70%, 90%, 100%, 5 minutes in each), delipidated in xylene (10 minutes) and coverslipped in Permount (or any other xylene diluted adhesive).

Analysis Note

Control
CONTROL ANTIGEN: Included free of charge with the antibody is 40 μg of control antigen (lyophilized powder in phosphate buffered saline, pH 7.4, containing 5% sucrose and 0.025% sodium azide). The stock solution of the antigen can be made up using 200 μL of sterile deionized water. For negative control, preincubate 1 μg of peptide with 1 μg of antibody for one hour at room temperature. Optimal concentrations must be determined by the end user.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
