Biological Activity for L-Ascorbic acid
L-Ascorbic acid is an inhibitor of Cav3.2 channels (IC50 = 6.5 μM); displays no effect on Cav3.1 or Cav3.3 channels heterologously expressed in HEK 293 cells. Also enhances the generation of induced pluripotent stem cells (iPSCs) from mouse and human somatic cells by increasing reprogramming efficiency. Commonly used antifade reagent in live cell microscopy. Naturally occurring antioxidant.
For more information about how L-Ascorbic acid may be used, see our protocol: Highly Efficient Generation of CiPSCs from MEFs

Stem Cells Scientific Review
Written by Kirsty E. Clarke, Victoria B. Christie, Andy Whiting and Stefan A. Przyborski, this review provides an overview of the use of small molecules in the control of stem cell growth and differentiation. Key signaling pathways are highlighted, and the regulation of ES cell self-renewal and somatic cell reprogramming is discussed. Compounds available from Tocris are listed.
Stem Cell Workflow Poster
Stem cells have potential as a source of cells and tissues for research and treatment of disease. This poster summarizes some key protocols demonstrating the use of small molecules across the stem cell workflow, from reprogramming, through self-renewal, storage and differentiation to verification. Advantages of using small molecules are also highlighted.
