- Extra Details:
- Presenilin1 was initially identified a marker of susceptibility to early-onset Alzheimer’s disease. In addition to PEN2, nicastrin and APH-1, Presenilin1 forms the g-secretase protein complex, a membrane-bound aspartyl protease that can cleave certain proteins at peptide bonds buried within the hydrophobic environment of the lipid bilayer. This cleavage is responsible for a key step in signaling from several cell-surface receptors and is thought to be required for the generation of the neurotoxic amyloid peptides that are central to the pathogenesis of Alzheimer’s disease. Like the tumor necrosis factor-a-converting enzyme (TACE) and the b-site cleavage enzyme (BACE) protease families, g-secretase will cleave the amyloid precursor protein (APP), but within the intramembrane region of APP, resulting in either the non-toxic p3 (from the a and g cleavage site) or the toxic Ab amyloid peptide (from the b and g cleavage site). It is thought that accumulation of the Ab peptide is the precursor to Alzheimer's disease. Multiple isoforms of presenilin1 are known to exist. This antibody has no cross-reactivity to presenilin2. Applications: Suitable for use in ELISA, Western Blot, Immunofluorescence and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-2ug/ml Immunofluorescence: 20ug/ml Immunohistochemistry (Formalin fixed paraffin embedded): 2.5ug/ml Optimal dilutions to be determined by the researcher.
