CloneID: SC16.25
Antigen Long Description: The original antibody was generated by immunizing three strains of mice (Balb/c, CD-1 and FVB) with recombinant human DLL3-Fc or with human DLL3-His fusion constructs.
Buffer Composition: PBS with 0.02% Proclin 300.
Available Custom Conjugation Options: AP, HRP, Fluorescein, APC, PE, Biotin Type A, Biotin Type B, Streptavidin, FluoroProbes 647H, Atto488, APC/Cy7, PE/Cy7
Uniprot Accession No.: Q9NYJ7
Specificity Statement: This antibody binds human DLL3 in the N-terminal domain. Cross-reacts with cynomolgus monkey DLL3 with no binding to mouse/rat DLL3. Delta-like protein 3 (DLL3) 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 characterization of this antibody to human DLL3 was done using ELISA. Binding affinity of mouse IgG antibody for human DLL3 is Kd= less than 0.2 nM. This antibody can bind human and cynomolgus monkey DLL3 expressed on surface of 293 cells via flow cytometry. This antibody can mediate killing of tumor cells expressing DLL3. Humanized version of this antibody is also available on request (US9089615).
