半乳糖可作为酵母、微生物培养的诱导型碳源,本品采用 0.22μm 滤膜过滤除菌,可直接添加进培养基使用。
注意事项:
1、未开封试剂室温可保存 1 年;长期储存建议置于- 20℃ 冷冻保存,开封后若溶液浑浊染菌,请立即弃用。
2、半乳糖溶液严禁高压蒸汽灭菌,高温会造成糖分降解、溶液发黄失效。
Galactose is an inducible carbon source for yeast and microbial culture. This product is sterilized with a 0.22 μm filter and can be directly added to culture medium.
Precautions:
1、Unopened reagent can be stored at room temperature for 1 year. Long-term storage is recommended at -20℃. Discard the solution once turbidity or contamination is found after opening.
2、Autoclaving is forbidden for galactose solution, since high temperature will lead to sugar degradation, yellow discoloration and invalidation.
