AHP2250 specifically recognises human APH-1A (gamma-secretase subunit APH-1A), otherwise known as anterior pharynx defective 1 homolog A, an integral transmembrane protein, and member of the APH-1 family, which is predominantly located in the endoplasmic reticulum and cis-Golgi, and is an essential component of the endoprotease gamma-secretase complex.
The gamma-secretase complex, consisting of APH-1 (APH-1A or APH-1B), presenilin-1 or -2 (PSEN1 or PSEN2), nicastrin (NCSTN), and Pen-2 (PEN2), plays a vital role in the evolutionarily conserved Notch signaling pathway, by catalyzing the intramembrane S3 cleavage of ligand-activated Notch receptor proteins (Notch1-4), resulting in the generation and release of an activated NICD fragment, which then translocates to the nucleus and activates the transcription of downstream effector genes.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
AHP2250 detects a band of approximately 26kDa in Human cerebral cortex cell lysates.
Storage
Store at +4oC or at -20oC if preferred.
Storage in frost-free freezers is not recommended.
This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
18 months from date of despatch.
Antiserum Preparation
Antiserum to human APH-1A was raised by repeated immunisation of goats with highly purified antigen. Purified IgG was prepared by affinity chromatography.
