樣品液(ye)的(de)(de)配(pei)制:用DMSO(Merck)溶解后,加入PBS(-)配(pei)成的(de)(de)100μmol/L的(de)(de)溶液(ye)或者均(jun)勻(yun)的(de)(de)混(hun)懸液(ye),然后用DMSO的(de)(de)PBS(-)稀(xi)釋,最終濃度分(fen)別為0.1,1,10,20,40,60,80,100μmol/L。

將抗腫瘤(liu)藥(yao)物(wu)5-氟尿嘧啶(ding)(5-FU)以(yi)同樣的條(tiao)件配成對照(zhao)品(pin)溶液。

細胞培養:貼壁生長腫瘤細胞細胞培養于含10%滅活新生牛血清和青霉素、鏈霉素(各100萬U/L)的1640培養液中,置于37℃,5%CO2,飽和濕度的二氧化(hua)碳(tan)培養(yang)(yang)箱中培養(yang)(yang)。細胞(bao)貼(tie)壁生長,每2~3天傳代1次(ci),傳代時首先倒出培養(yang)(yang)液(ye),PBS洗2次(ci),胰(yi)酶消(xiao)化(hua)后,加(jia)入新(xin)鮮(xian)的培養(yang)(yang)液(ye)吹打均勻(yun),調整細胞(bao)至適當濃(nong)度移入新(xin)的培養(yang)(yang)瓶(ping)中,添加(jia)培養(yang)(yang)液(ye)至適量。取對數生長期細胞(bao)用于實驗。
