Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

Sterol glucosyltransferases have different functional roles in Pichia pastoris and Yarrowia lipolytica.[Pubmed: 14585290]

METHODS AND RESULTS:
Mutants of the methanol-utilizing yeast Pichia pastoris and the alkane-utilizing yeast Yarrowia lipolytica defective in the orthologue of UGT51 (encoding sterol glucosyltransferase) were isolated and compared. These mutants do not contain the specific ergosterol derivate, Ergosterol glucoside. We observed that the P. pastoris UGT51 gene is required for pexophagy, the process by which peroxisomes containing methanol-metabolizing enzymes are selectively shipped to and degraded in the vacuole upon shifting methanol-grown cells of this yeast to glucose or ethanol. PpUGT51 is also required for other vacuole related processes. In contrast, the Y. lipolytica UGT51 gene is required for utilization of decane, but not for pexophagy.
CONCLUSIONS:
Thus, sterol glucosyltransferases play different functional roles in P. pastoris and Y. lipolytica.
