APPLICATION NOTES FOR MAB343

IMMUNOHISTOCHEMISTRY

1) Prepare paraformaldehyde-fixed paraffin sections. Wash twice for 5 min in xylene to deparaffinize. Wash sections for 5 min in a descending series of alcohol solutions (100%, 96%, 90%, 80%, 70%, 50%, 30%).

2) Wash sections 3 times in distilled water.

3) Wash in TBS (50 mM Tris-HCl, 150 mM NaCl, pH 7.6). To block endogenous peroxidase wash with methanol containing 0.6% H2O2 (v/v) and 10 % horse serum (v/v) for 5 min at room temperature.

4) Wash sections for 5 min in TBS.

5) Incubate sections with MAB343 (diluted in TBS containing 10% horse serum (v/v)) overnight at +4°C or for 2 hours at 37°C in a humid chamber.

6) Wash sections 3 times in TBS for 5 min..

7) Detect with standard secondary antibody detection system (PAP, ABC, etc.).

8) Wash sections in TBS.

9) Embed sections and examine.
