(C) Generation of pluripotent stem cell from Yamanaka factors-induced OG2-MEFs under treatment of diverse chemical compounds. Images of GFP+ colonies were taken on day 10 post-infection. VPA, 0.5 mmol/L. CHIR99021, 3 μmol/L. Repsox, 1 μmol/L. (D) Quantification of GFP+ colonies in (C). All figures are representative of three independent experiments (n = 3). All data are presented as mean ± SD. *P < 0.05, **P < 0.01 vs. DMSO

|Description||RepSox is a potent and selective inhibitor of the TGFβR-1/ALK5 with IC50 of 23 nM and 4 nM for ATP binding to ALK5 and ALK5 autophosphorylation in cell-free assays, respectively.|
RepSox inhibits ATP binding to ALK5 and ALK5 autophosphorylation with IC50 of 23 nM and 4 nM, respectively. RepSox inhibits TGF-β induced cellular PAI-1 luciferase activity with IC50 of 18 nM.  RepSox is able to successfully replace Sox2 in reprogramming by inhibiting transforming growth factor-β (Tgf-β) signaling, which in turn induces Nanog expression. Effect of RepSox inducing reprogramming does not require chromatin remodeling. RepSox is found to be efficient at generating iPSCs. 
|In vivo||RepSox is able to be contribute to forming chimeric embryos in vivo when injected into blastocysts. A one-day treatment with RepSox is sufficient to replace transgenic Sox2. |

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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.
