  • Untransfected HEK293 cells surface (green line) and transfected Human DLL3 HEK293 stable cells surface (red line) were stained with anti-DLL3 antibody (rovalpituzumab-like) (2µl/1*106 cells), washed and then followed by FITC-conjugated anti-Human IgG1 Fc antibody and analyzed with flow cytometry.
  • The Binding Activity of DLL3 with Anti-DLL3 Recombinant Antibody.
    Activity: Measured by its binding ability in a functional ELISA. Immobilized DLL3 (CSB-MP3536MOV) at 2 μg/mL can bind Anti-DLL3 Recombinant Antibody(CSB-RA882142A1HU), the EC50 is 1.625-2.702 ng/mL.
  • The Binding Activity of DLL3 with Anti-DLL3 Recombinant Antibody.

Description

DLL3 (Delta-like protein 3) serves as a critical ligand in the Notch signaling pathway, playing essential roles in somite segmentation during embryonic development and neural differentiation. Unlike other Notch ligands, DLL3 functions primarily as an inhibitor of Notch signaling, making it a compelling target for researchers investigating developmental biology, neuroscience, and increasingly, cancer biology where its aberrant expression has garnered significant therapeutic interest.

This recombinant monoclonal antibody against human DLL3, clone 7B7, offers the reproducibility and consistency that demanding research applications require. Produced using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability inherent in traditional hybridoma production, ensuring your experimental results remain comparable across studies and over time. The human IgG1 isotype format and affinity-chromatography purification deliver a reagent optimized for sensitive detection methods.

Validation studies demonstrate robust performance in both flow cytometry and ELISA applications. Flow cytometric analysis clearly distinguishes between untransfected HEK293 cells and HEK293 cells stably expressing human DLL3, confirming specific surface detection of the target protein. Functional ELISA testing reveals excellent binding characteristics, with EC50 values in the low nanogram per milliliter range against immobilized DLL3 protein, indicating high-affinity target recognition suitable for quantitative applications.

For flow cytometry experiments, recommended dilutions of 1:50 to 1:200 provide flexibility to optimize signal-to-noise ratios across different experimental conditions. Whether your research focuses on Notch pathway regulation, neural development, or cell surface marker characterization, this antibody provides a reliable tool for investigating DLL3 biology in human samples.

Target Background

Function
Inhibits primary neurogenesis. May be required to divert neurons along a specific differentiation pathway. Plays a role in the formation of somite boundaries during segmentation of the paraxial mesoderm.
Gene References into Functions
  1. these results reveal that DLL3 is expressed in tumor specimens from most patients with small cell lung cancer PMID: 29290251
  2. Results indicated that DLL3 expression was silenced in hepatocellular carcinoma (HCC) cells by DNA methylation and was more readily affected by histone acetylation than histone methylation (H3K9me2 or H3K27me3). PMID: 29512761
  3. our results indicated epidermal growth factor-like domain multiple 7 protein participates in growth hormone-secreting pituitary adenoma proliferation and invasion regulation via Notch2/DLL3 signaling pathway. These findings raised the possibility that epidermal growth factor-like domain multiple 7 protein might serve as a useful biomarker to assess growth hormone-secreting pituitary adenoma invasion and prognosis PMID: 28705113
  4. The Dll3 was rarely detectable in the para-carcinoma tissues, but positive in 82.1% of non-small cell cancer tissues. PMID: 28007595
  5. Both global haplotype and individual haplotype analyses showed that the haplotypes of SNP1/SNP2/SNP3/SNP4/SNP5 did not correlate with the disease (P >0.05). Together, these data suggest that genetic variants of the DLL3 gene are not associated with CS in the Chinese Han population. PMID: 27472720
  6. DLL3 was silenced by methylation in human human hepatocellular carcinoma and it negatively regulates the growth of human hepatocellular carcinoma cells. PMID: 23337976
  7. We suggest that the three human DLL3 mutations associated with spondylocostal dysplasia are also functionally equivalent to the Dll3(neo) null allele in mice. PMID: 11923214
  8. mutations in DLL3 cause a consistent pattern of abnormal vertebral segmentation in spondylocostal dysostosis PMID: 12746394
  9. no novel or previously described mutations are present in our cohort, indicating that DLL3 mutations may not be a major cause of congenital scoliosis. PMID: 15717203
  10. The intracellular region of Notch ligands Dll1 and Dll3 regulates their trafficking and signaling activity PMID: 18676613
