Extra Details:
DELTA-4 (also called delta 4 precursor, delta ligand 4 precursor, Delta-like protein 4, DLL4, Drosophila Delta homolog 4 and notch ligand DLL4 precursor) is a homolog of the Drosophila delta protein. The delta gene family encodes Notch ligands that are characterized by a DSL domain, EGF repeats, and a transmembrane domain. DELTA-4 plays a role in the Notch signaling pathway and activates Notch-1 and Notch-4. DELTA-4 is a membrane protein that is expressed in the vascular endothelium.
Formulation:
0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2
Host:
Rabbit
Immunogen:
Anti-DELTA-4 antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region of Human DELTA-4.
Isotype:
IgG
Physical State:
Liquid
Reactivities:
Human, Mouse
Shipping Conditions:
Dry Ice
Specificity:
DELTA-4 affinity purified antibody is directed against human DELTA-4. The product was affinity purified from monospecific antiserum by immunoaffinity chromatography. A BLAST analysis was used to suggest reactivity with this protein from human based on 100% homology for the immunogen sequence. However, cross reactivity is expected with mouse, rat and chimpanzee DELTA-4 based on a 91% homology to th
Storage Conditions:
-20[o]C aliquoted. Aliquot. Avoid freeze/thaw cycles.

Type:
Antibody: Polyclonal Antibody
Rockland's Affinity Purified anti-Delta-4 antibody was used at 20 ug/ml to detect Delta-4 in a variety of tissues including colon, liver, skeletal muscle, ovary, pancreas, prostate, testes, thymus, tonsil and uterus. In contrast to reported findings, no staining was observed in vascular tissue. This image shows Delta-4 staining of human ovary. Tissue was formalin-fixed and paraffin embedded.

Western Blot of Rabbit anti-Delta-4 antibody. Lane 1: mouse pancreatic tissue (p/n W10-000-T023). Load: 20 ug per lane. Primary antibody: Delta-4 antibody at 1:500 for overnight at 4°C. Secondary antibody: HRP-labeled Goat anti-Rabbit IgG secondary antibody (p/n 611-103-122) at 1:5,000 for 1 hour at RT. A chemiluminescence system was used for signal detection using a 3 min exposure time. Block: 5% Goat Serum (p/n B304) overnight at 4°C. Predicted/Observed size: 74 kDa, 70 kDa for Delta 4. Other band(s): none.
ELISA results of purified Rabbit anti-DELTA-4 Antibody tested against BSA-conjugated peptide of immunizing peptide. Each well was coated in duplicate with 0.1ug of conjugate. The starting dilution of antibody was 5ug/ml and the X-axis represents the Log10 of a 3-fold dilution. This titration is a 4-parameter curve fit where the IC50 is defined as the titer of the antibody. Assay performed using 3% fish gel, Goat anti-Rabbit IgG Antibody Peroxidase Conjugated (Min X Bv Ch Gt GP Ham Hs Hu Ms Rt & Sh Serum Proteins) (p/n 611-103-122) and TMB ELISA Peroxidase Substrate (p/n TMBE-1000).

Primary antibody: DELTA-4 antibody at 1:1,000 overnight at 4°C. Secondary antibody: Peroxidase rabbit secondary antibody (p/n 611-103-122) at 1:40,000 for 30 min at RT. Block: Blocking Buffer for Fluorescent Western Blotting (p/n MB-070) for 30 min at RT. Predicted/Observed size: 74 kDa, 74 kDa for DELTA-4. Other band(s): Not Identified.
