求翻译：1. 5 MTT实验 制备细胞悬液，调整细胞浓度为1×105，实验分成药物处理组：全反式维甲酸（用二甲基亚砜配制）1，10，100，1000nmol/L组；紫杉醇（用无水乙醇配制）1，10，100，1000nmol/L组；无水乙醇组（无水乙醇和培养基）；二甲基亚砜组（二甲基亚砜和培养基）共10组，和阴性对照组（培养基），每组设6个孔。根据各药物浓度的结果，进一步分成全反式维甲酸和紫杉醇联合应用组。取96孔培养板，每孔加入上述浓度的细胞悬液100ul，按以上分组进行实验，将紫杉醇和全反式维甲酸用DMEM培养液稀释，使终浓度分别为：1，10，100，1 000nmol/L，将盛有细胞悬液和上述药物的96孔板放置在37是什么意思？

1.5 MTT experimental preparation cell suspended liquid, adjustment cell concentration for 1x105, experimental into drug processing Group: full anti-type dimension formic acid (with II methyl Asia sulfone preparation) 1,10,100,1000nmol/L Group; yew alcohol (with no water ethanol preparation) 1,10,100,1000nmol/L group; no water ethanol Group (no water ethanol and medium); II methyl jiya sulfone Group (II methyl Asia sulfone and medium) total 10 group, and negative controlled group (medium), each group set 6 a hole. Depending on the concentration results, further divided into all-TRANS Retinoic acid and paclitaxel combined with application groups. Take the 96-well culture plates, each hole to join the above concentration cell suspension 100ul, grouped by more than experimental, paclitaxel and all-TRANS Retinoic acid diluted with DMEM culture fluid, concentration, respectively: 1,10,100,1 000nmol/L, containing cell suspension and 96-well plate placed above drug cultivation in 37
