If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

General description
Moreover, Tocofersolan acts as an inhibitor of P-glycoprotein (P-gp or MDR1) substrate-induced ATPase activity in cell-free assays. It has demonstrated efficacy against resistant K562 cells by binding to urokinase-type plasminogen activator, a crucial enzyme for cancer cell migration and invasion. Additionally, Tocofersolan inhibits tyrosine kinase, a key player in cancer cell development, offering potential applications in metabolomics and biochemical research. Its ability to enhance the absorption of water-insoluble agents and other fat-soluble vitamins positions it as a promising compound for formulation and drug delivery research.
Application
Biochem/physiol Actions
Tocopherol polyethylene glycol 1000 succinate (TPGS) may be used to create biodegradable polymers and antioxidant surfactants.
TPGS exerts anti-tumor activity in MCF-7 and breast cancer cells by downregulating anti-apoptotic proteins.[2]
TPGS finds its application as an emulsifier in the preparation of poly(lactic-co-glycolic acid) (PLGA) particles for DNA labelling, produces particles of uniform size, high encapsulation efficiency, increases hydrophilicity and prevents aggregation of particles.[1]
Features and Benefits
- Can be used in Metabolomics and Biochemical research
- High-quality compound suitable for multiple research applications

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Hello, I would like to know how to correctly handle this product: is it required (due to possible inhomogeneity) to melt the entire bottle before dispensing or it is not the case? also, how many melting cycles are safe to be performed?
1 answer-
This product is listed as a waxy solid. Most lots are released as chunks which can be weighed up without melting. However, if small, precise amounts are required, melting to liquify is suitable. The Tocopherol in this complex is esterified and quite stable, however it may be best to aliquot working volumes to minimize reheating. The density at 45 °C is 1.06 g/mL. See the image below to review published information on the thermal stability with repeated heat cycles.
