What is FOXO4-DRI?

FOXO4-DRI is a modified peptide that blocks the interaction between FOXO4 and p53. It’s built from D-amino acids in reverse order, which makes it resistant to enzymes.

It’s studied as a senolytic, meaning a compound that clears senescent cells.

Research on FOXO4-DRI

Baar and colleagues reported in Cell (2017) that FOXO4-DRI pushed senescent cells into apoptosis and restored fur density, fitness and kidney function in aged and fast-aging mice.

A 2020 study tested it on senescent Leydig cells in aged mice.

Preparing FOXO4-DRI in the lab

The vial holds FOXO4-DRI as a dry, freeze-dried cake. To use it, dissolve it in bacteriostatic water, letting it run slowly down the side of the glass so it doesn’t hit the powder directly. Swirl or roll the vial until it’s clear. Shaking can damage peptides, so skip it.

The amount of water you add sets the concentration. For example, adding 2mL of bacteriostatic water to a 2mg vial gives 1mg per mL. Write the volume and the date on the label so anyone picking up the vial later knows what’s in it.

We sell bacteriostatic water in 30mL vials, and acetic acid solution for the few peptides that don’t dissolve well in water.

Choosing a FOXO4-DRI vial size

The vial comes in 2mg, 5mg and 10mg. The contents are the same apart from the amount, so the choice comes down to how much your study needs and how quickly you’ll use a mixed vial.

Mixed peptides don’t last as long as dry ones, so several smaller vials can work out better than one large one if you’re running a slow study.

FOXO4-DRI quality and testing

Every batch of FOXO4-DRI is checked with liquid chromatography-mass spectrometry (LC-MS) before it goes on sale. LC-MS separates a sample into its parts and identifies each one by mass, so it confirms what the compound is and how much of the sample it makes up. The current batch tested at 99% or higher.

Small differences between batches are normal, so write the batch number from the label into your records. If something looks wrong when your order arrives, like discoloured powder or a cloudy solution, set it aside and don’t use it.

Storage and handling

Keep it in the fridge at 2 to 8°C and don’t freeze it. Once mixed, keep the vial in the fridge and use it within a few weeks. Unmixed vials keep much longer, so only reconstitute what you need. Label anything you decant with the compound, amount and date, and keep it out of reach of children and pets.

Common questions about the FOXO4-DRI peptide vial

Does FOXO4-DRI come with water to mix it?

No. The vial holds only the freeze-dried powder. Add bacteriostatic water to your order if you don’t already have some.

How long does mixed FOXO4-DRI last?

Kept in the fridge, most reconstituted peptides are good for a few weeks. Unmixed vials last much longer, especially in the fridge or freezer.

Is the FOXO4-DRI peptide vial in stock?

Yes. Every option on this page is in stock and ready to ship.
