Storage Instructions

All products from Apex Health Performance are manufactured using a lyophilization (freeze-drying) process. This method is designed to maintain product integrity and allows vials to remain stable during shipping for approximately 3–4 months.

Once a vial is reconstituted with bacteriostatic water, it should be stored in the refrigerator to help maintain stability. Under these conditions, reconstituted material is generally considered stable for up to 30 days.

Lyophilization is a dehydration technique in which compounds are frozen and then exposed to low pressure. This causes the water in the vial to sublimate directly from solid to gas, leaving behind a stable, crystalline white structure. This powder can be kept at room temperature until reconstitution.

Upon receipt, products should be stored away from heat and light. For short-term use, refrigeration at approximately 4°C (39°F) is suitable. For long-term storage (several months to years), vials may be placed in a freezer at approximately -80°C (-112°F). Freezing is the preferred method for preserving product stability over extended periods.

FOXO4 Facilitates Diabetic Retinopathy by Mediating KLF7 Transcription and Affecting the TLR4/MyD88/NF-κB Pathway.

Applied biochemistry and biotechnology 2026

Kruppel-like factor 7 (KLF7) takes part in high-glucose (HG)-prompted retinal pigment epithelial cell (RPE) apoptosis in vitro, the molecular mechanisms of KLF7-mediated DR pathogenesis are poorly studied. The toll-like receptor 4 (TLR4)/myeloid differentiation primary response 88 (MyD88)/nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway was assessed by western blot and the NF-κB inhibitor BAY 11-7085.

FOXO4-DRI regulates endothelial cell senescence via the P53 signaling pathway.

Frontiers in bioengineering and biotechnology 2025

This study innovatively focuses on the mechanism by which FOXO4-DRI induces apoptosis in senescent endothelial cells, demonstrating that it functions by activating the p53/BCL-2/Caspase-3 signaling pathway to promote selective apoptosis of these cells. Additionally, it investigates changes in endothelial cell function in senescent endothelial cells induced by oxygen-glucose deprivation (OGD), as well as the protein expression and interaction in the FOXO4-P53 signaling pathway.

FOXO1 promotes cancer cell growth through MDM2-mediated p53 degradation.

The Journal of biological chemistry 2024

FOXO1 is a transcription factor and potential tumor suppressor that is negatively regulated downstream of PI3K-PKB/AKT signaling. Paradoxically, FOXO also promotes tumor growth, but the detailed mechanisms behind this role of FOXO are not fully understood.

Bioinformatics procedure for investigating senolytic (anti-aging) agents: A digital signal processing technique.

Aging medicine (Milton (N.S.W)) 2023

We found that enhanced senescence 2 (ES2) has a higher affinity for CR3 and BDB than FOXO4 and DRI, and that the interaction between CR3 and BDB is crucial for aging. Our findings are consistent with previous studies and reveal new insights into the mechanisms of senescence and senolytics.

Smurf2-Mediated Ubiquitination of FOXO4 Regulates Oxygen-glucose Deprivation/Reperfusion-induced Pyroptosis of Cortical Neurons.

Current neurovascular research 2023

This study sought to explore the molecular mechanism of Smurf2-mediated forkhead box O4 (FOXO4) ubiquitination in oxygen-glucose deprivation/ reperfusion (OGD/R)-induced pyroptosis of cortical neurons. Smurf2 overexpression promoted LDH release, reduced NLRP3, GSDMD-N, and cleaved-caspase-3 proteins, and decreased IL-1β and IL-18 concentrations.
