- SynonymNOTCH1,Notch 1,hN1,TAN1
- SourceHuman NOTCH1, Fc Tag (NO1-H5255) is expressed from human 293 cells (HEK293). It contains AA Ala 19 - Gln 526 (Accession # P46531-1).Predicted N-terminus: Ala 19Request for sequence
- Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 80.0 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human NOTCH1, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.

The purity of Human NOTCH1, Fc Tag (Cat. No. NO1-H5255) was more than 85% and the molecular weight of this protein is around 190-205 kDa verified by SEC-MALS.

Immobilized Human DLL4, His Tag (Cat. No. DL4-H5227) at 5 μg/mL (100 μL/well) can bind Human NOTCH1, Fc Tag (Cat. No. NO1-H5255) with a linear range of 1-8 ng/mL (QC tested).

Loaded Human NOTCH1, Fc Tag (Cat. No. NO1-H5255) on Protein A Biosensor, can bind Human DLL4, His Tag (Cat. No. DL4-H5227) with an affinity constant of 67.5 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).

Loaded Human NOTCH1, Fc Tag (Cat. No. NO1-H5255) on Protein A Biosensor, can bind Human DLL1, His Tag (Cat. No. DL1-H52H8) with an affinity constant of 290 nM as determined in BLI assay (ForteBio Octet Red96e) (Routinely tested).
- BackgroundNOTCH1 Interacts with DNER, DTX1, DTX2 and RBPJ/RBPSUH. Alsointeracts with MAML1, MAML2 and MAML3 which act as transcriptional coactivators for NOTCH1. The NOTCH1 intracellular domain interacts with SNW1; the interaction involves multimerized NOTCH1 NICD and is implicated in a formation of an intermediate preactivation complex which associates with DNA-bound CBF-1/RBPJ. The activated membrane-bound form interacts with AAK1 which promotes NOTCH1 stabilization. Functions as a receptor for membrane-bound ligands Jagged-1 (JAG1), Jagged-2 (JAG2) and Delta-1 (DLL1) to regulate cell-fate determination. Involved in the maturation of both CD4+ and CD8+ cells in the thymus. Important for follicular differentiation and possibly cell fate selection within the follicle. During cerebellar development, functions as a receptor for neuronal DNER and is involved in the differentiation of Bergmann glia.
