Specificity Statement: This antibody binds human Delta-like protein 3 (DLL3), which is a transmembrane protein that belongs to the Delta/Serrate/Lag-2 (DSL) family of Notch ligands. Mature human DLL3 consists of a 466 amino acid (aa) extracellular domain (ECD) with one DSL domain and six EGF-like repeats, a 21 aa transmembrane segment, and a 105 aa cytoplasmic domain. It is an inhibitory Notch ligand that is highly expressed in small cell lung cancer (SCLC) and other neuroendocrine tumors but minimally expressed in normal tissues. It is therefore being explored as a potential therapeutic target in SCLC.
Application Notes (Clone): The binding affinity to human DLL3 that is comparable with Rovalpituzumab. The binding characterization of this antibody for human DLL3 was done using ELISA. This antibody was capable of binding DLL3 expressed on the surface of H446 and H524 small cell lung cancer cell lines using flow cytometry (CN114057880).
