Product Overview

SB431542 is an inhibitor of the transforming growth factor-beta 1 (TGF-β1) activin receptor-like kinases (ALKs). It is a selective and potent inhibitor of ALK-4, -5 and -7. SB431542 inhibits endogenous activin and TGF-β signaling without affecting more divergent BMP signaling utilizing ALK-1, -2, -3, and -61,2. SB431542 stimulates proliferation, differentiation, and sheet formation of endothelial cells derived from embryonic stem cells3.

Stemolecule SB431542 in Solution is a ready to use 10 mM stock solution for stem cell culture.

Size
5 mg (10 mM)
Alternate Name(s)
SB-431542
4-[4-(1,3-benzodioxol-5-yl)-5-pyridin-2-yl-1H-imidazol-2-yl]benzamide
Chemical Formula
C22H16N4O3
Molecular Weight
384.4
CAS Number
301836-41-9 (anhydrous)
Purity
Greater than 98% by HPLC analysis
Formulation
10 mM solution of SB431542 in DMSO (5 mg in 1.3 ml)
Storage and Stability
Store solution at -20°C protected from light. Stable for 6 months from date of receipt when stored as directed.
Quality Control
The purity of SB431542 was determined by HPLC analysis. The accurate mass was determined by mass spectrometry. Cellular toxicity of SB431542 was tested on mouse embryonic stem cells.
Handling
Before opening, briefly centrifuge the vial to ensure full recovery of sample. Aliquotting the stock solution is recommended to avoid repetitive freeze-thaw cycles. For cell culture, the media should be prewarmed prior to adding the reconstituted compound. Note: for most cells, the maximum tolerance to DMSO is less than 0.5%.
Concentration
10 mM in DMSO
