Rabbit Monoclonal Antibody to Human Nicastrin
Nicastrin, also known as NCSTN, is a single-pass type I membrane protein which belongs to the nicastrin family. Nicastrin was named after the Italian village Nicastro, reflecting the fact that Alzheimers disease was described in 1963 after studying descendants of an extended family originating in the village of Nicastro that had Familial Alzheimers Disease (FAD). Nicastrin is a protein that is part of the gamma secretase protein complex, which is one of the proteases involved in processing amyloid precursor protein (APP) to the short Alzheimers disease-associated peptide amyloid beta. Nicastrin may represent a stabilizing cofactor required for the assembly of the gamma-secretase complex. The other proteins in the complex are presenilin, which is the catalytically active component of the complex, APH-1, and PEN-2. Nicastrin itself is not catalytically active, but instead promotes the maturation and proper trafficking of the other proteins in the complex, all of which undergo significant post-translational modification before becoming active in the cell. Nicastrin has also been identified as a regulator of neprilysin, an enzyme involved in the degradation of amyloid beta fragment.
Human Nicastrin / NCSTN. No cross-reactivity with human cell lysate ( 293 cell line ) in WB and ELISA.
Recombinant Human Nicastrin / NCSTN Protein
Western blot; ELISA
Western blot: This antibody can be used at 1-2 μg/mL with the appropriate secondary reagents to detect Human NCSTN in WB. Using a DAB detection system, the detection limit for Human NCSTN is approximately 10 ng/lane under non-reducing conditions and 2 ng/lane under reducing conditions.Direct ELISA: This antibody can be used at 0.1-0.2 μg/mL with the appropriate secondary reagents to detect Human NCSTN. The detection limit for Human NCSTN is approximately 0.0049 ng/well.
This antibody was obtained from a rabbit immunized with purified, human cell-derived, recombinant Human Nicastrin / NCSTN
0.2 μm filtered solution in PBS with 5% trehalose
