Product Details
Background
Delta-like ligand 4 (DLL4), also know as Delta-4, is a homologue of the Drosophila delta protein, and functions as a transmembrane bound ligand to the notch receptor Notch1. DLL4 is expressed in the vasculature and plays a critical role in vascular development. It is induced by vascular endothelial growth factor (VEGF), as a negative feedback regulator to regulate angiogenic sprouting and promote the formulation of a differentiated vascular network. DLL4 has been found to be strongly expressed in tumor vessels of clear-cell renal tumors and bladder cancer, and inhibition of DLL4 results in increased vascular proliferation but defective maturation. This in turn leads to a decrease in tumor growth, with no apparent toxicity.
Application
To ensure optimal assay performance, AREX recommends conducting reagent titration tailored to each testing system for optimal detection results.
*Results are sample-specific. Please refer to your local assay conditions and test parameters for reference.

FAQs
What are the main types of research antibodies and how do they differ?
Research antibodies are mainly divided into monoclonal antibodies and polyclonal antibodies. Monoclonal antibodies typically offer higher specificity and better batch-to-batch consistency, while polyclonal antibodies often provide stronger affinity but may show more variation between batches. The choice depends on your specific experimental needs.
How can I tell if a research antibody is suitable for my experiment?
It is recommended to carefully review the product datasheet for validated applications, species reactivity, recommended dilutions, and published references. For new antibodies, performing a small-scale validation with positive control samples is usually helpful.
Can improper storage of research antibodies affect experimental results?
Yes. Antibodies are sensitive to temperature, repeated freeze-thaw cycles, and contamination. Improper storage may lead to reduced activity, increased background, or weaker signals. It is best to follow the storage instructions provided in the product datasheet.
Why doesn’t the recommended dilution in the datasheet work well in my experiment?
The recommended dilution is based on the supplier’s test conditions. Factors such as sample type, fixation method, and detection system in your lab can influence the optimal working concentration. Performing a dilution series optimization in your own system is often necessary.
What precautions should I take when using a newly purchased research antibody for the first time?
It is advisable to briefly centrifuge the antibody (especially concentrated or lyophilized ones), then perform a small-scale pilot experiment using the recommended conditions. Recording the batch number and usage date is also helpful for future tracking.
