General description
Dieses nichtsteroidale Triphenylethylenderivat unterdrückt das Tumorwachstum und ist Berichten zufolge bei Tieren karzinogen und teratogen. Darüber hinaus kann TC den Knochen auch vor durch Östrogenmangel bedingten Knochenverlust schützen und den Cholesterinspiegel im Plasma senken. Zudem wurde es mit der Entwicklung von Leberkrebs bei Ratten in Verbindung gebracht. Weitere Wirkungen von TC umfassen die Verringerung des Plasmaspiegels des insulinähnlichen Wachstumsfaktors, die Induktion der Ausschüttung von transformierendem Wachstumsfaktor-β in Zellen in der Tumorumgebung und die Hemmung der Lipidperoxidation der Membran, wahrscheinlich durch Verringerung der Membranfluidität.
Application
- im MTS-Assay (3-(4,5-Dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium-Assay) und Kristallviolett-Färbe-Assay zur Bestimmung der Zellviabilität[1] [2]
- zur Induktion einer Dicer-Ablation bei Dicer-konditionierten Mäusen zur Untersuchung der Auswirkungen eines Dicer-Mangels auf die Differenzierung und Funktion von Adipozyten[3]
- zur Untersuchung der biologischen Wirkungen auf die glukokortikoidresistente (GC) Zelllinie Jurkat, derivatisiert aus akuter lymphoblastischer Leukämie der T-Zell-Linie (T-ALL)[4]
- zur Untersuchung der physiologischen Auswirkungen der Tamoxifen-Behandlung auf die POA des Hypothalamus, vermittelt durch den Östrogenrezeptor-alpha (ERα) bei Mäusen[5]
- zur Induktion der Cre-Rekombinase-Aktivität zur Genmanipulation
- zur Förderung der Rekombination des ect2-Flox-Allels in Mausorganen
- zur Untersuchung der Wirkung auf die Lipopolysaccharid(LPS)-vermittelte Aktivierung von Mikroglia

Hello, Thank you for your product. According to my protocol, I have to dissolve Tamoxifen in the corn oil at the final concentration of 40 mg/ml and feed my mice with that. However, it's insoluble. How can I resolve it? Thank you, Hossein
1 answer-
This product is soluble in chloroform (50 mg/mL, clear, colorless to faintly yellow), 2-propanol, DMSO (10 mM), ethanol, methanol and propylene glycol. Kindly review the information on the product datasheet available at this link: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/product/documents/389/852/t5648pis.pdf
Corn oil has also been used as a vehicle for tamoxifen as cited by Whitfield J, Littlewood T, Soucek L. Tamoxifen administration to mice. Cold Spring Harb Protoc. 2015 Mar 2;2015(3):269-71. doi: 10.1101/pdb.prot077966. PMID: 25734062; PMCID: PMC6773604.

If I want to use 20mg of tamoxifen, could I only dissolve part of tamoxifen and then store the rest of the powder at refrigerator? Or do I have to dissolve all vial at once?
1 answer-
Tamoxifen is relatively stable. Any required amount can be weighed up for use as needed and the bottle resealed. The powder should be stable for at least two years when stored desiccated at 2-8C, and protected from light.

What is the stability of tamoxifen (e.g., Product No. T5648) once in solution?
1 answer-
Solutions of tamoxifen are sensitive to UV light. According to C.A. O'Brian et al., [Cancer Res. 45, 2462 (1985)], tamoxifen when dissolved in DMSO can be stored at -20°C in the dark. We generally recommend making the solution fresh right before each use.

What is the solubility of tamoxifen, Product No. T5648?
1 answer-
Tamoxifen is tested for solubility in chloroform at a concentration of 50mg/mL. This yields a colorless to faint yellow solution. Tamoxifen is practically insoluble in water. It has been reported to be soluble in methanol, ethanol, 2-propanol and propylene glycol. This product is also reported to be soluble in DMSO at 10mM concentration. Reference for DMSO solubility: Wong, K.R., et al., Am. J. Physiol. Heart Circ. Physiol., 277, H1403-H1409 (1999). Please also see the product information sheet (under Documents, above) for more information on the solubility of this product.
