Technical Data
Delta 4 (Delta-like protein 4, DLL4, Drosophila Delta homolog 4, notch ligand DLL4 precursor)
Delta 4 (Delta 4 Precursor, Delta Ligand 4 Precursor, Delta-like Protein 4, DLL4, Drosophila Delta Homolog 4, 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.

Suitable for use in ELISA, Immunohistochemistry and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:5000-1:25,000
Immunohistochemistry (FFPE): 10-20ug/ml; Detects Delta 4 in a variety of tissues including colon, liver, skeletal muscle, ovary, pancreas, prostate, testes, thymus, tonsil and uterus. In contrast to reports, no staining was observed in vascular tissue.
Western Blot: 1:500-1:2500. Recognizes a band ~74kD.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
