| 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. |

Genotoxicity of a variety of pyrrolizidine alkaloids in the hepatocyte primary culture-DNA repair test using rat, mouse, and hamster hepatocytes.[Pubmed:4005849]
Cancer Res. 1985 Jul;45(7):3125-9.
Seventeen pyrrolizidine alkaloids were studied with the hepatocyte primary culture-DNA repair test using rat hepatocytes. DNA repair synthesis was elicited by 15 alkaloids, including 11 of unknown carcinogenicity, i.e., senecionine, seneciphylline, jacobine, epoxyseneciphylline, senecicannabine, acetylfukinotoxin, syneilesine, dihydroclivorine, ligularidine, neoligularidine, and Ligularizine. The positive results with these alkaloids of unknown carcinogenicity suggest that they are possibly genotoxic carcinogens. The two pyrrolizidine alkaloids that did not elicit DNA repair were retronecine which lacks a necic acid component and ligularinine which lacks the unsaturated double bond at the 1,2-position of the pyrrolizidine ring. Five pyrrolizidine alkaloids, retronecine, monocrotaline, seneciphylline, senkirkine, and clivorine, were also tested in the DNA repair test with hamster or mouse hepatocytes. These alkaloids, except retronecine, showed a positive response in the test with hamster hepatocytes, but in the test with mouse hepatocytes clivorine in addition to retronecine was also negative. The results indicate a species difference in liver bioactivation of pyrrolizidine alkaloids, implying that there could be species differences in their carcinogenic activities.
