Product Specifications

Immunogen

This whole rabbit serum was prepared by repeated immunizations with a synthetic peptide corresponding to an internal region near amino acid residues 2390-2415 of human Notch-2 (the total protein is 2471 aa). A residue of cysteine was added to the amino terminal end to facilitate coupling. (Uniprot: Q04721)

Reactivity Notes

This antiserum is directed against human Notch-2. The peptide sequence shows 100% alignment with human, dog and chimpanzee sequence. Only one (1) amino acid difference is found in mouse and this change is non-conservative. Based on the sequence we expect this antibody to react as well with rat and mouse Notch-2. No specific information is available for other reactivities.

Scientific Data Images for Notch-2 Antibody - BSA Free

Western Blot: Notch-2 Antibody [NB600-879]

Western Blot: Notch-2 Antibody [NB600-879] - Analysis of a band at 110 kDa corresponding to active Notch 2 protein (arrowhead). Analysis was performed for Notch 2 expression using 100ug of total protein lysate obtained from human mesothelial SV40 cells transfected with a plasmid encoding a constitutively active Notch 2 (intra cellular Notch 2). Lanes 1-3 contain lysate 24 h (1), 48 h (2), and 72 h (3) post transfection. Lanes 4-6 are the corresponding control cells (untransfected) taken at similar time points. The band at about 110kD represents active Notch 2. This band is not seen in the control cell. The intracellular domain of Notch 2 has a predicted band size of 110kD, corresponding to this band. Protein cell lysates were run on a 10% SDS-page gel, blotted onto Hybond C membrane, blocked overnight in PBS-Tween 20 supplemented with 5% Non-fat Milk and probed with anti-Notch 2 at a 1:400 dilution. ECL was used as visualization method.

Immunohistochemistry-Paraffin: Notch-2 Antibody [NB600-879]

Immunohistochemistry-Paraffin: Notch-2 Antibody [NB600-879] - Diluted 1:500 to detect Notch-2 in human kidney tissue. Tissue was formalin fixed and paraffin embedded. No pre-treatment of sample was required. The image shows the localization of antibody as the precipitated red signal, with a hematoxylin purple nuclear counter stain.

Notch-2 Antibody

Anti-Notch 2 antibody was diluted 1:500 to detect NOTCH 2 in human kidney tissue. Tissue was formalin fixed and paraffin embedded. No pre-treatment of sample was required. The image shows the localization of antibody as the precipitated red signal, with a hematoxylin purple nuclear counter stain.

Applications for Notch-2 Antibody - BSA Free

Application

Recommended Usage

ELISA

1:30000-1:90000

Immunohistochemistry

1:200-1:800

Immunohistochemistry-Paraffin

1:500

Western Blot

1:400-1:2000

Application Notes

This antibody has been tested for use in ELISA and western blot. For western blot experiments, one can expect a band of ~110 kDa in size corresponding to active Notch 2 in the appropriate cell lysate. A 1:500 dilution was effective for staining FFPE human kidney tissue by Immunohistochemistry (IHC). Specific conditions for reactivity should be optimized by the end user.

Background: Notch-2

Synthesized in the endoplasmic reticulum as an inactive form which is proteolytically cleaved by a furin-like convertase 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 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 to release a notch-derived peptide containing the intracellular domain (NICD) from the membraneFunctions as a receptor for membrane-bound ligands Jagged1, Jagged2 and Delta1 to regulate cell-fate determination. Upon ligand activation through the released notch intracellular domain (NICD) it forms a transcriptional activator complex with RBP-J kappa and activates genes of the enhancer of split locus. Affects the implementation of differentiation, proliferation and apoptotic programs.
