Carbohydrate preferences of mammalian cells.

Carbohydrate preferences of mammalian cells can be utilized to biochemically distinguish between different cell lines. Ninety-three carbohydrates were examined of which (a) 15 supported cell proliferation and (b) 42 were toxic or growth inhibitory. The present investigation has employed an enzymatic system to eliminate trace glucose levels from reagents and glucose generated by serum enzymes.
