摘要
目的探索油红O在斑马鱼体内脂质染色中的技术方法。方法取受精后4d的斑马鱼幼鱼,4%多聚甲醛固定12h后,用油红0工作液对整鱼进行染色,比较不同的染色时间及不同的染料浓度对油红O染色效果的影响。结果斑马鱼脑组织、卵黄囊、鱼鳔及血管内的脂质被油红O染色。油红0液浓度0.3%、染色时间3h时斑马鱼整鱼油红O染色效果较好。结论油红O可对斑马鱼体内的脂质进行染色,可用于斑马鱼脂代谢研究。
Objective To explore the technical characteristics of Oil Red O staining of lipids in zebrafish.Methods 4d- post- fertilization zebrafish larvae were fixed in 4%paraformaldehyde for 12 h and then dyed with Oil Red 0.The effects of different dyeing time lengths and dye concentrations on the staining result were compared.Results The lipids in the brain tissue,yolk sacs,swim bladders and blood vessels of zebrafish were able to be stained with Oil Red 0.The best result was observed when the larve was stained with 0.3%Oil Red 0 for 3h.Conclusion Oil Red O is able to stain the lipids in zebrafish and be used for the study of lipid metabolism in zebrafish.
