Description

FOX04-DRI

FOXO4-DRI (FOXO4-D-Retro-Inverso) is a high-purity synthetic peptide designed as a potent Senolytic agent. In the field of advanced aging research and regenerative medicine, FOXO4-DRI is distinguished by its unique ability to selectively induce apoptosis (programmed cell death) in senescent cells—often referred to as “zombie cells.” It functions by competitively inhibiting the interaction between the FOXO4 transcription factor and the p53 tumor suppressor protein. By displacing p53 from the nucleus of senescent cells, FOXO4-DRI allows p53 to trigger mitochondrial-mediated apoptosis, effectively clearing damaged cells without harming healthy tissue. This provides researchers with a groundbreaking experimental model to investigate systemic rejuvenation, the reversal of age-related tissue dysfunction, and the molecular mechanisms of life extension.

Our FOXO4-DRI is synthesized in an ISO 9001:2015 certified environment utilizing advanced D-Retro-Inverso (DRI) peptide technology. This DRI modification—using D-amino acids in a reversed sequence—significantly enhances the peptide’s stability and resistance to proteolytic degradation (proteolysis), ensuring a much longer biological half-life than standard L-peptides. We achieve an ultra-high chemical purity of ≥99%, verified by HPLC and Mass Spectrometry (MS).

Key Features & Quality Assurance

Advanced Lyophilization Stability

Our proprietary vacuum-sealing process ensures the FOXO4-DRI powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure protects the complex peptide sequence during long-term storage and ensures rapid reconstitution.

DRI-Technology for Enhanced Potency

The D-Retro-Inverso modification ensures that the peptide is not recognized or broken down by standard proteases in the research model, providing superior bioavailability and consistent experimental outcomes.

Reconstitution & Storage

Reconstitution Guide

• Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the FOXO4-DRI cake is at the base.

• Solvent: Reconstitute with Sterile Water or PBS.

• Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.

Storage Protocols

• Long-term: Store at -20°C (Maintains potency for up to 24 months).

• Short-term: Stable at 2–8°C for up to 3 months.

• Post-Reconstitution: Store at 2–8°C and utilize within 7-10 days for optimal results.
