Potential Applications in Research (RUO)

Strictly for laboratory research. No health, diagnostic, or therapeutic claims.

FOXO4–p53 interaction assays — competitive binding (pull-down, fluorescence anisotropy, ITC) to quantify displacement of FOXO4 from p53.
In-vitro senescence models — evaluate p53 localization, caspase-3/7 activation, SA-β-gal staining, and SASP gene panels under controlled induction protocols.
Selectivity profiling — compare activity across FOXO family domains; assess influence of p53 post-translational states on binding.
Method development — establish RP-HPLC/LC–MS(/MS) identity, purity, recovery, and forced-degradation stability across buffers and temperatures.

Quality, Storage & Handling

Every lot is confirmed by HPLC (purity) and MS (identity); the on-vial QR links to the batch COA. Independent U.S. labs verify purity, quantity, and endotoxin.

Reconstitution: Bring vial to room temp; add sterile water or buffer to the vial wall and gently swirl/invert. Avoid vigorous vortexing; brief sonication can help stubborn pellets.
Aliquoting: Prepare single-use aliquots immediately after dissolving to minimize freeze–thaw exposure.
Controls: Include sequence-scrambled or D/L control peptides per your SOP for mechanistic interpretation.

Shipping & Fulfillment

Ships with validated cold-chain packaging. In-stock orders placed before the daily cutoff ship the same day. 2-Day FedEx/UPS is standard, with overnight options available. Automated text/email updates included; international shipping available where permitted.

Compliance & RUO Disclaimer

For laboratory research only. Not a drug, cosmetic, food, or household chemical. Not for human or animal use, ingestion, diagnostic, or therapeutic applications. Purchasers warrant appropriate qualifications and compliance with applicable regulations and institutional policies.

FAQs

Is this the TAT-fused version used in some studies?: Unless stated on the COA, this listing is the FOXO4-DRI core peptide (no CPP). Some publications used a TAT fusion for uptake; custom variants may be available upon request.
Why do formula/mass values vary online?: Values depend on exact sequence variant and counter-ion content. The free-base form is commonly reported around 5.36 kDa; acetate/TFA content or CPP fusions change these numbers. Always confirm on your lot COA.
What purity do you provide?: Each 10 mg vial is ≥99% by HPLC with MS identity confirmation; third-party testing is performed on every lot (COA via on-vial QR).
How should I reconstitute it?: Dissolve in sterile water or a compatible buffer; gently invert until fully dissolved. If sterility is required by your SOP, 0.22 µm filter and aliquot to avoid repeat freeze–thaw.
