Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.
We will provide viable cells that proliferate on revival.

FOXO3A also known as FOXO3 or 1e2 is a transcription factor with a molecular weight of approximately 71 kDa. It belongs to the Forkhead box O family of proteins. This protein plays an important role in the regulation of transcription in response to oxidative stress and growth stimuli. FOXO3A is expressed in a variety of tissues including liver muscle and brain where it contributes to a wide range of cellular processes related to stress resistance and metabolism. Scientists frequently study FOXO3A using techniques like FOXO3A ELISA and apply FOXO3A anticuerpos in research to understand its function more intricately.
FOXO3A acts as a regulator of genes involved in cell cycle arrest apoptosis and DNA repair. It is not part of a simple protein complex but works closely with multiple factors to influence cellular homeostasis. Significantly FOXO3A controls the expression of Bcl-2 a protein important for cell survival and the protein p27 which is important for cell cycle control. FOXO3A's activity modulates cellular longevity and impacts stress responses highlighting its abundant biological functions.
FOXO3A integrates into the PI3K/AKT and the insulin signaling pathways both essential for cellular metabolism and proliferation control. In the PI3K/AKT pathway FOXO3A functionally links with proteins such as AKT and PTEN where its activity can be inhibited by AKT-mediated phosphorylation. In doing so it supports a balance between cell survival and apoptosis allowing the cell to adjust to growth conditions and external stressors effectively.
FOXO3A is linked to cancer and neurodegenerative diseases. In cancer alterations in FOXO3A activity or expression can affect tumor growth and resistance to oxidative stress often involving interactions with proteins like MDM2. Similarly in neurodegenerative disorders such as Alzheimer's disease FOXO3A modifies responses to oxidative damage potentially tied to proteins like Tau. Both instances highlight the role of FOXO3A as a versatile modulator that can influence the progression and management of various diseases.
