Indicated PN and MES spheres were shown expressing GFP under the control of a 7 × TCF/LEF optimal promoter cassette (7 × TOP) and constitutively expressed nuclear mCherry. PN 84 and MES 1123 were treated with Wnt3a (200 ng/ml), indomethacin (Indo; 20 μM), or a control (vehicle). Scale bar, 100 μm. Bar graph, quantification of fluorescent signal of GFP (TOP-GFP) versus mCherry (PGK-H2BmCherry). The percentage of GFP- and mCherry-positive spheres was determined by FACS.

|Description||Indomethacin (Indometacin) is a nonselective COX1 and COX2 inhibitor with IC50 of 0.1 μg/mL and 5 μg/mL, respectively, used to reduce fever, pain, stiffness, and swelling.|
Indomethacin inhibits transcription of a beta-catenin/TCF-responsive reporter gene in a dose dependent manner. Indomethacin also downregulates the beta-catenin/TCF transcriptional target cyclin D1. Indomethacin attenuates the transcription of beta-catenin/TCF-responsive genes, by modulating TCF activity without disrupting beta-catenin/TCF complex formation. 
|In vivo||Indomethacin increases BrdU+ cells of all lineages and reduces microglial/monocyte activation in rats after focal cerebral ischemia.  Indomethacin (7.5 mg/kg, one injection) produces acute injury and inflammation in the distal jejunum and proximal ileum that are maximal at three days and completely resolves within one week. Indomethacin (two daily subcutaneous injections) produces a more extensive and chronic inflammation that lasts in an active form in more than 75% of the rats for at least two weeks.  Indomethacin (4ppm) reduces tumor yield by 78% in SKH:HR-1-hrBr hairless mice.  Indomethacin (20 mg/kg, orally) increases the total area of gastric erosions and concentration of lipid peroxides in the gastric mucosa of rats. Indomethacin increases the alpha-tocopherol:total cholesterol ratio in serum. Indomethacin inhibits the increases in gastric mucosal erosions and lipid peroxides in the gastric mucosa, and the reduction of serum alpha-tocopherol. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
