FOXO4-DRI is a synthetic D-retro-inverso peptide supplied exclusively for controlled laboratory research. It is used in experimental systems examining molecular interactions involving the FOXO4 transcription factor and the p53 signaling protein.
FOXO4 and p53 are studied in connection with transcriptional regulation, cellular stress signaling, cell-cycle control, genomic stability, and senescence-associated molecular pathways. FOXO4-DRI provides researchers with a defined peptide material for conducting in vitro assays, analytical evaluations, and controlled biochemical experiments involving these signaling systems.
Every lot is accompanied by analytical documentation identifying the tested material and reporting lot-specific quality data. Researchers should consult the applicable Certificate of Analysis before beginning an experiment.
The primary concern for peptide researchers today is product purity. Nord-sci guarantees our product purity by performing independent testing of our products and providing those certifications for our customers in our product descriptions.

All products are produced using lyophilization (freeze-drying), a preservation method that allows peptides to remain fully stable during shipping for approximately 3-4 months. Once a peptide has been reconstituted with bacteriostatic water, it must be refrigerated to maintain integrity. After reconstitution, peptides typically remain stable for up to 30 days when stored properly.
Lyophilization, also referred to as cryodesiccation, is a specialized dehydration process in which peptides are first frozen and then exposed to a low-pressure environment. This causes the water within the vial to transition directly from a solid to a vapor (sublimation), leaving behind a dry, crystalline white material known as a lyophilized peptide. In this powdered form, peptides may be safely stored at room temperature until they are ready to be reconstituted with bacteriostatic water.
After delivery, peptides should be protected from heat and light. If use is expected within the near future (whether days, weeks, or a few months) refrigerated storage below 4°C (39°F) is generally sufficient. Lyophilized peptides are commonly stable at room temperature for several weeks or longer, making short-term ambient storage acceptable when use is anticipated within that timeframe.
For extended storage, ranging from several months to multiple years, freezing is strongly recommended. Storage at -80°C (-112°F) offers optimal long-term stability and helps preserve peptide structure and quality over time.

FOXO4-DRI (10mg) is a synthetic research peptide intended for controlled in vitro experimentation and analytical evaluation. The material is studied in laboratory systems involving the FOXO4-p53 interaction, transcription-factor activity, cellular stress signaling, cell-cycle regulation, and senescence-associated molecular pathways.
Cellular senescence is an experimentally defined state in which a cell undergoes persistent cell-cycle arrest while retaining measurable metabolic and signaling activity. Laboratory investigations use cellular, biochemical, and molecular assays to characterize the regulatory networks associated with this state.
FOXO4-DRI is not a pharmaceutical product, dietary supplement, food, cosmetic, or clinical material. No dosing, administration, or application guidance is provided.

FOXO4-DRI is a synthetic peptide developed for laboratory investigation of molecular interactions involving FOXO4 and p53. FOXO4 belongs to the forkhead box O family of transcription factors, while p53 is a regulatory protein examined in cell-cycle, genomic-stability, and stress-response research.
Experimental programs involving this peptide may use binding assays, cultured-cell systems, protein-interaction studies, or other controlled analytical methods to examine FOXO4-p53 pathway activity. Results can vary according to the selected model, assay conditions, material concentration, exposure period, detection method, and laboratory controls.
Research involving FOXO4-DRI should remain limited to properly equipped laboratory environments and appropriately qualified personnel. References to molecular pathways describe areas of scientific investigation and do not indicate a clinical or consumer application.
