Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.

Buffer

Lyophilized from a 0.2 μm filtered 20 mM Tris-HCl, 0.5 M NaCl, 6% Trehalose, pH 8.0

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Protein FAQs

Storage Condition

Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

Shelf Life

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Lead Time

3-7 business days

Notes

Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description

DLL3 is an atypical Notch ligand that functions as a cis-inhibitor of Notch signaling, making it a high-value target in antibody development programs for neuroendocrine tumors. This recombinant human DLL3 partial construct (aa 27–492) is expressed in mammalian cells with a C-terminal 6xHis tag, preserving native-like glycosylation critical for accurate binding studies. Functional ELISA validation demonstrates that immobilized DLL3 at 2 μg/mL binds anti-DLL3 recombinant antibody with an EC50 of 1.102–1.707 ng/mL, confirming robust receptor-ligand interaction suitable for antibody screening, epitope binning, and SPR-based affinity measurements. With purity exceeding 85% by SDS-PAGE and endotoxin levels below 1.0 EU/μg by LAL testing, this preparation meets the quality thresholds commonly required for functional cell-based Notch signaling assays and serves as a reliable positive control in immunoassay development workflows.

Applications : Antigen

Review: I performed an ELISA experiment using the CSB-MP882142HU product, and the EC50 was measured to be 2.267-3.180 ng/ml. The results show that the protein has excellent binding activity. In subsequent immune experiments, the mouse serum showed high titers, the sensitivity of the screened antibodies was high, and the affinity was good. These findings suggest that the antigen performs well and meets expectations.

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

these results reveal that DLL3 is expressed in tumor specimens from most patients with small cell lung cancer PMID: 29290251
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
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
The Dll3 was rarely detectable in the para-carcinoma tissues, but positive in 82.1% of non-small cell cancer tissues. PMID: 28007595
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
DLL3 was silenced by methylation in human human hepatocellular carcinoma and it negatively regulates the growth of human hepatocellular carcinoma cells. PMID: 23337976
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
mutations in DLL3 cause a consistent pattern of abnormal vertebral segmentation in spondylocostal dysostosis PMID: 12746394
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
