"Age, Undone" Senescence

FOX04-DRI and Epithalon are both studied in cellular-senescence research, but from two entirely different mechanistic angles, FOX04-DRI through disrupting the FOXO4-p53 protein interaction associated with senescent cells, and Epithalon through telomerase-activity research. The Senescence kit bundles both together.

Cellular senescence, the state in which cells stop dividing but resist normal cell death, is studied through more than one mechanism in the research literature. This kit pairs two of the most-cited angles: FOX04-DRI, which targets a specific protein interaction associated with senescent-cell persistence, and Epithalon, which is studied for telomerase activity, a separate mechanism tied to the genomic-stability side of cellular aging.

What's Included in This Kit

• Vial 1, FOX04-DRI (10mg): FOXO4-p53 protein interaction disruption in senescent-cell research.
• Vial 2, Epithalon (10mg): telomerase activity and cellular senescence research.

FOX04-DRI: Targeting a Specific Protein Interaction

FOX04-DRI is a cell-penetrating peptide designed specifically to disrupt the FOXO4-p53 protein interaction, a mechanism studied in senescent-cell research because that interaction is associated with how senescent cells resist apoptosis. Because it targets a defined protein-protein interaction rather than a broader pathway, FOX04-DRI is often used in research designs that want a more mechanistically isolated intervention point.

Epithalon: A Separate, Genomic-Stability Mechanism

Epithalon is a synthetic tetrapeptide related to the naturally occurring pineal peptide epithalamin. Its research relevance is telomerase activity, a mechanism studied separately from FOX04-DRI's protein-interaction focus but frequently discussed in the same senescence and cellular-aging literature. Telomere-length maintenance and senescent-cell persistence are both studied as contributing factors to the same broader aging phenotype, even though the two mechanisms operate independently of each other at the molecular level.

Why This Kit Carries a Premium Price Point

FOX04-DRI carries a higher per-vial cost than most other research peptides on the site, reflected in this kit's overall price relative to similarly sized two-peptide kits elsewhere in the Peptide Bundles collection. This cost difference is a function of FOX04-DRI's synthesis complexity rather than an arbitrary premium, and it applies whether the peptide is purchased individually or, as here, bundled with Epithalon.

Senescence Research as a Distinct Category

Cellular senescence is studied somewhat separately from the broader cellular-aging category that compounds like NAD+ or SS-31 fall under. Where general cellular-aging research often concerns energy metabolism and mitochondrial function, senescence research specifically concerns why certain cells stop dividing yet fail to undergo normal programmed cell death, and what happens as those senescent cells accumulate in tissue over time. FOX04-DRI and Epithalon were selected for this kit because both sit within that narrower senescence-specific research question, rather than the wider metabolic-aging category covered elsewhere in the Peptide Bundles collection.

Both vials ship individually labeled with compound name, strength, and batch lot number and are not co-formulated. Each is independently HPLC-verified for identity and purity before batch release, with Certificates of Analysis available per component on request, matching the documentation provided when either peptide is purchased individually.
