REACH authorisation
Abcam has not and does not intend to apply for the REACH Authorisation of customers' uses of products that contain European Authorisation list (Annex XIV) substances.
It is the responsibility of our customers to check the necessity of application of REACH Authorisation, and any other relevant authorisations, for their intended uses.
Lysate preparation:
Our lysates are made using RIPA buffer to which we add a protease inhibitor cocktail and phosphatase inhibitor cocktail (ratio: 300:100:10).
This means that the protein of interest is denatured.
If you require a native form of the protein please use the live cell version. Please refer to our lysis protocol for further details on how our lysates are prepared.
User storage instructions:
Lyophilizate may be stored at 4°C. After reconstitution, store at -20°C for short-term storage or -80°C for long-term storage.

The 14-3-3 sigma protein also known as SFN is a member of the 14-3-3 family of proteins. It plays a major role in cellular processes by regulating various signaling pathways. This protein has a molecular mass of about 28 kDa. The expression of 14-3-3 sigma is most notable in epithelial cells and it participates in cell cycle control. It interacts with a wide range of signaling molecules emphasizing its involvement in cellular regulation.
Biological function summary
14-3-3 sigma contributes to cell cycle arrest and apoptosis. As part of a complex it interacts with other proteins to ensure proper cell division and prevent abnormal growth. It binds to phosphorylated serine/threonine residues on its target proteins influencing their activity and function. By doing this it exerts control over cell cycle checkpoints and influences DNA damage response mechanisms.
Pathways
14-3-3 sigma interacts with several pathways that are critical for maintaining cell stability and response to stress. It participates in the PI3K/AKT pathway working closely with proteins like AKT1 to facilitate cell survival and growth suppression under stress conditions. Its involvement in this pathway ties it to the regulation of cell proliferation and survival interconnecting with broader cellular networks.
Disruptions in 14-3-3 sigma function are linked to cancer and neurodegenerative diseases. In cancer its downregulation or loss leads to unchecked cell division contributing to tumor progression. In neurodegenerative diseases such as Alzheimer's the protein's interaction with tau phosphorylation processes affects disease progression. Furthermore it interacts with proteins like p53 emphasizing its role in tumor suppression and cellular stress responses.
