| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Neutral lipids in the cells and cell envelope fractions of aerobic baker's yeast and anaerobic brewer's yeast.[Pubmed:1091369]
Chem Phys Lipids. 1975 Feb;14(1):15-32.
The neutral lipids from whole cells and cell envelopes of aerobic Saccharomyces cerevisiae and anaerobic Sacch. carlsbergensis and the cell walls isolated from the cell envelopes were analysed. The effect of anaerobiosis was particularly clear on the neutral lipid composition of the plasma membrane. Compared to the anaerobic membrane, the aerobic membrane contained more C16:1, C18:1 and other unsaturated fatty acids, more total sterol, more than ten times as much ergosterol and less than one tenth as much squalene, reflecting differences between the aerobic and anaerobic whole cellmthe main sterol in the aerobic membrane ergosterol, was mainly in the free form, whereas zymosterol, 24(28)-Dehydroergosterol, epi- or fecosterol and lanosterol were predominantly esterified. In contrast, the anerobic membrane contained small amounts of biosynthetic sterol precursors of ergosterol (mainly esterified), and was clearly richer in saturated fatty acids having a greater variation in chain length and in 18:2 acid. Both plasma membranes contained a considerable amount of triacyglycerols, while the amount of lower acylglycerols was clearly higher in the anaerobic plasma membrane. The lipid composition of both cell walls were relatively similar, consisting mainly of triacylglycerols and lower acylglycerols.
Nystatin-resistant mutants of yeast: alterations in sterol content.[Pubmed:5122815]
J Bacteriol. 1971 Oct;108(1):69-73.
Mutants of the genes nys1 and nys3 differ from sensitive strains (nys(+)) in their sterol content. Ultraviolet absorption spectra of the nonsaponifiable material extracted from cells of nys(+) demonstrated the presence of ergosterol and 24(28)-Dehydroergosterol. In nys1 mutants, the spectrum suggests the presence of a new sterol. The absorption spectrum of extracts from nys3 mutants indicates absence of both ergosterol and 24(28)-Dehydroergosterol and presence of another new sterol. Conversion of nys(+) and nys3 to petite results in loss of 24(28)-Dehydroergosterol in the former and the new sterol in the latter, whereas the new sterol in nys1 is only reduced. The sterols in ethanol-grown cells of all genotypes are essentially the same as is found for growth on glucose. With the exception of nys3 grown on ethanol, the mutants do not appear to be at a disadvantage compared to wild type.
