Anti-APH1, ID (Gamma-secretase Subunit APH-1A, APH-1a, APH-1a, Aph-1alpha, Presenilin-stabilization

APH1 was initially identified as a component of the Notch pathway in C. elegans. Along with nicastrin, PEN2, and presenilin-1 APH1 is an essential component of the ysecretase complex which cleave the amyloid precursor protein (APP) at what are known as the y and ysites and can lead to the accumulation of the Amyloid b peptide Abcleavage product that is associated with Alzheimer's disease. APH1 exists in at least three distinct isoforms with APH1a as the principal isoform present in the ysecretase complex. Mice deficient in this isoform, but not the other two, were lethal at E10.5, with impaired vascular and neural development observed. Despite its predicted molecular weight, APH1 protein often migrates at aberrant locations in SDS-PAGE. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-1ug/ml, Immunohistochemistry (Formalin fixed paraffin embedded): 5ug/ml, Optimal dilutions to be determined by the researcher. Positive Control: Human Brain Tissue Lysate, Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
