RESUMO
Polyclonal antibodies elicited by injection into rabbits of a nystatin-bovine serum albumin conjugate were reactive with both nystatin and amphotericin B. Upon labeling of polyene-treated Saccharomyces cerevisiae sterol auxotrophs grown on various sterols, nystatin reacted specifically with ergosterol, while amphotericin B did not react preferentially with ergosterol, cholesterol, or cholestanol. Time course labeling experiments demonstrated the rate of ergosterol transport into cholesterol-grown cells.
