Specificity
Reacts with intact full-length Alzheimer precursor protein (APP) and selectively with the cytoplasmic carboxyl fragment of APP 643-695. Epitope has reportedly been mapped in this paper http://www.impub.co.uk/abs/W386.html
Immunogen
Carboxyl fragment of APP 643-695 / Jonas.
Epitope: APP 643-695 C-terminal fragment
Application
Immunohistochemistry on paraffin sections: 10-20 μg/mL * See protocol below.
Western blot: 10 μg/mL
Optimal working dilutions must be determined by end user.
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.
Western blot: 10 μg/mL

In order to access beta-secretase (BACE1), and enzyme strongly implicated in the cause of Alzheimer's disease, inhibitors must possess sufficient lipophilicity to traverse two lipid bilayers. Current drug candidates, which are almost totally peptide-derived, are thus inefficient because cell permeability
