273 kDa. ( Note )


This antibody reacts with mouse Notch constructs present in lysates of HEK 293 cells.  Only the cleaved intracellular (activated) form (NICD) is detected.  No reactivity is detected against mouse N2, N3 or N4.  The immunogen epitope is only exposed after gamma secretase cleavage and is not accessible in the uncleaved form.




0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2 and 0.1% (w/v) Sodium Azide


Store as concentrated solution. Centrifuge briefly prior to opening vial. For short-term storage (1-2 weeks), store at 4ºC. For long-term storage, aliquot and store at -20ºC or below. Avoid multiple freeze-thaw cycles.

Notch 1,Aos5,Aovd1,Tan1,Hn1,Notch1


Notch 1 is synthesized in the endoplasmic reticulum as an inactive form, which is proteolytically cleaved by a furin-like convertase (S1 cleavage) in the trans-golgi network before it reaches the plasma membrane to yield an active, ligand-accessible form. Cleavage results in a C-terminal fragment N(TM) and a N-terminal fragment N(EC). Following ligand binding, it is cleaved (S2 cleavage) by TNF-alpha converting enzyme (TACE) to yield a membrane-associated intermediate fragment called Notch extracellular truncation (NEXT). This fragment is then cleaved by presenilin-dependent gamma-secretase (S3 cleavage) to release the intracellular domain (NICD) from the membrane.

GTX28925 WB Image

Rabbit anti-Human NOTCH 1 (Cleaved N Terminal) was used at a 1:500 dilution to detect mouse Notch 1 by Western blot in 293 cells transiently transfected with myc-tagged mouse Notch. Bound antibody was detected with a 1:10,000 dilution of HRP conjugated Goat anti Rabbit IgG, and color development. Lane M: markers. Lane 1: No transfection. Lane 2: N1 (mouse deleted extracellular domain)-myc. Lane 3: N1 (mouse intracellular domain)-myc. Lane 4: N2 (mouse deleted extracellular domain)-myc. Lane 5: N2 (mouse intracellular domain)-myc. Lane 6: N3 (mouse deleted extracellular domain)-myc. Lane 7: N3 (mouse intracellular domain)-myc. Lane 8: N4 (mouse deleted extracellular domain)-myc. Lane 9: N4 (mouse intracellular domain)-myc. Lane 10: N1 (mouse deleted extracellular domain)(V to G)-myc.
