ANTI-PRESENILIN-1 ANTIBODY NT CLONE HPS1-NT

Specificity

Recognizes Presenilin-1, human. By Western blot the antibody recognizes a predominant 32 kDa polypeptide in a variety of samples, including PC12 cells transfected with human PS1 complementary DNA, brain biopsy specimens from demented patients, and postmortem samples of frontal neucortex from Familial Alzheimer′s Disease cases, late-onset Alzheimer′s disease cases, and cases of other degenerative disorders. Immunohistochemical studies of control brains revealed that PS1 is expressed primarily in neurons, with the protein localizing in the soma and dendritic processes. In contrast in FAD and sporadic Alzheimer′s disease cases, PS1 immunoreactivity was present in the neuritic component of senile plaques as well as in neurofibrillary tangles. Localization of PS1 immunoreactivity in familial and sporadic Alzheimer′s disease suggest that genetically heterogeneous forms of the disease share a common pathophysiology involving PS1 protein.

Immunogen

A fusion protein antigen containing the N-terminus of human PS-1 (residues 21-80) fused to GST.

Epitope: N-terminus

Application

Immunohistochemistry: rat pups and 24 old month rats were perfused for 10 minutes with 100-200mL of 4% PFA 0.3% glutaraldehyde and 0.1% CaCl2 in 0.1M PBS pH 7.4. Vibratome sections were blocked with 3% normal serum and permeabilized with 0.1% triton X-100.{Neuroscience 2003 120:405-423}.

Immunoblotting: 1:250-1:500. Recommend blocking buffer is TBS containing 5% non fat milk and 0.01% Tween 20. It is recommended that you also dilute the antibody in this blocking buffer. Incubate with the MAB1563 for 1 to 2 hours at room temperature or overnight at 4°C.
