Fruit Fly Colony Care for Lab Studies
Description
Fruit fly colony care keeps Drosophila melanogaster healthy for lab studies. These flies are common model organisms in life science research. A working colony needs more than simple food and a container. It depends on careful husbandry and regular maintenance.
The first step is preparing the yeas...

果蝇研究上获得的成功还要归功于对这个极有价值的模式生物的饲养养和保存。接下来的视频将讨论给果蝇提供所需的营养，饲养容器和如何操作果蝇的一些必须环节。
尽管都认为果蝇如其名字一样是以水果为食，它的食物其实是腐烂发酵水果上的微生物，如酵母。在实验室里，为了便于操作，将果蝇的食物做了些改动。
现有几个配方里的基本成分都含有糖和酵母。以下的配方来自印第安纳大学伯明顿分校，该校因保存有大量不同品系的果蝇而闻名。其配方含:蒸馏水，酵母粉，豆粉，玉米粉，琼脂，玉米糖浆以及抑制霉菌和细菌生长的丙酸。将这些组分混合，加热，搅拌后用...
