| 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. |

| About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

| Shipping Condition | Packaging according to customer requirements(5mg, 10mg, 20mg and more). Ship via FedEx, DHL, UPS, EMS or other couriers with RT, or blue ice upon request. | ||
The Pencillium urticae
| Description | 1. Phyllostine appears to be their more immediate precursor, since PCMB-treated extracts of J2 converted Phyllostine but not isoepoxydon to these new metabolites. |

Patulin biosynthesis: the metabolism of phyllostine and isoepoxydon by cell-free preparations from Pencillium urticae.[Pubmed:43192]
Can J Microbiol. 1979 Aug;25(8):881-7.
Cell-free extracts of Penicillium urticae (NRRL 2159A), and its Pat- mutants, J2, J1, and S11, were found to contain significant NADP-dependent isoepoxydon dehydrogenase activity. This reversible interconversion of the epoxides (-)-Phyllostine and (+)-isoepoxydon occurred optimally at pH 5.8 and was completely inhibited by 1 mM p-chloromercuribenzoate (PCMB). The cytosol enzyme possessed specificity for both substrate and cofactor since neither (+)-epoxydon, an epimer of (+)-isoepoxydon, nor NADH was utilized. Cell extracts of the parent and of mutant J2, which is blocked before the epoxides in the patulin pathway, were found to convert Phyllostine and isoepoxydon to a number of unknown metabolites which appeared as yellow spots on thin-layer chromatograms after spraying with a chromogenic reagent. Extracts of mutant J1 were unable to carry out this conversion, while whole cells of mutant S11 accumulated what appeared to be these same 'yellow' compounds. Since PCMB-treated extracts of J2 converted Phyllostine but not isoepoxydon to these new metabolites, Phyllostine appeared to be their more immediate precursor. The relative positions of isoepoxydon and Phyllostine in the patulin pathway are discussed.
