For research use only. Not for human consumption.
FOXO4-DRI is a synthetic peptide derived from part of the FOXO4 transcription factor and redesigned in D-retro-inverso form: its sequence runs backwards and every amino acid is the D-enantiomer, which roughly preserves the side-chain arrangement of the original L-peptide while making it far less vulnerable to proteases. A cell-penetrating stretch is built in so the peptide can reach intracellular targets in cultured cells.
It comes as lyophilised powder in a sealed vial, with analytical documentation for the lot. Being a long and strongly charged peptide, it calls for careful planning of reconstitution and storage.

Questions about FOXO4-DRI
What is FOXO4-DRI?
A synthetic D-retro-inverso peptide based on the FOXO4 transcription factor, used in the lab as a senolytic tool that disrupts the FOXO4–p53 interaction reported in senescent cells.
What does “D-retro-inverso” mean?
The sequence is reversed and made entirely of D-amino acids instead of the natural L-forms. This keeps the side chains in approximately the same spatial arrangement while giving a protease-resistant backbone, so the peptide lasts longer in experiments.
Is the lot tested by an independent lab?
Yes. HPLC is used to determine purity and mass spectrometry to confirm identity for every lot, and the Certificate of Analysis can be viewed before you buy. Use the net peptide content stated on the COA when you calculate working concentrations.
Which size can I buy?
A single 10 mg lyophilised vial. At about 6053 g/mol, this peptide is so heavy that 10 mg equals far fewer moles than 10 mg of a short peptide like epitalon.
How do I reconstitute it?
Use sterile or bacteriostatic water, adding it gently down the inside of the vial and swirling rather than shaking. As the peptide is long and charged, give it extra time to dissolve and use low-binding labware to limit losses by adsorption.
