ingredient information
D Sorbitol
D-sorbitol is an acyclic polyol that is commonly added to media to allow growth of cells with a defective cell wall. Growth on media supplemented with 1M D-sorbitol results in a 35% increase in mean life span (Kaeberlein et al., 2002). Addition of 1M D-sorbitol to the growth media suppresses the short life-span of an mpt5 mutant (Kaeberlein and Guarente, 2002).
