我们使用了南京建成的胆固醇，甘油三酯和游离脂肪酸的试剂盒，样本为小鼠肝脏，试剂盒提供的步骤为使用生理盐水或者乙醇作为匀浆介质，3500rpm,10min;
然而我们发现生理盐水作为匀浆介质时,按此离心速度无法获得上清液；若加大离心速度以及延长离心时间，获得的上清液为白色，蛋白浓度检测出来浓度很高，效果十分不理想；若改为乙醇作为匀浆介质时，检测结果甘油三酯很高，游离脂肪酸浓度很低，不知是否涉及脂肪酯化的问题；
希望大家能给我提提建议，给点自己的妙招；或者是否有人提供好用的试剂盒？
1.我利用微乳法制备SLN，模型药物、三棕榈酸甘油酯、甘油、泊洛沙姆188，80度下融化，混合均匀，2000rpm搅拌状态下滴加1%PVA水相。冷却至室温时，表面有一层脂质析出。不断增加Lipid：surfacant的比例，当达到1:20时，当冷却至室温时，仍有脂质析出。
新人一枚，想问下各位大侠，有什么好的解决方案不？
在兔子上研究肝脏脂代谢，不知道什么细胞株合适，自己培养的担心不靠谱，不知道有没有做过这方面的，给提一些意见，感谢！
