Notes: The Stem Cell Small Molecule Screening Library contains more than 140 small molecules that are known either to induce differentiation, to maintain self-renewal and proliferation, or to improve the reprogramming efficiency of various stem cell populations. These compounds are supplied in a 96-well Matrix tube rack format as 10 mM stocks in DMSO. Stability data is not available for individual compounds as supplied in the screening library. Panels are routinely re-evaluated to include new catalog introductions as the research evolves.
