Cell Culture and Determination of Cytotoxicity. Metabolically active H4IIE rat hepatoma cells were grown in Dulbecco’s modified Eagle’s medium (4.5 g/L glucose, 2 mmol/L L-glutamine, 100 units/mL penicillin, 100 µg/mL streptomycin, and 10% fetal bovine serum)in a humidified atmosphere (37 °C, 5% CO2). The effect of isolated compounds on cell viability was determined using the MTT assay. The cells were plated in 96-multiwell plates with 10 000 cells/well.The cells were allowed to attach for 24 h and then treated with different concentrations of the compounds for 24 h. After this treatment the medium was changed and the cells were incubated for 3 h under cell culture conditions with 0.7 mg/mL MTT. After this incubation the cells were lysed with 50% EtOH/49% H2O/1% HOAc. The concentration of reduced MTT as a marker for cell viability was measured at 560 nm. Data are given as mean SEM of at least three independent experiments. The significance of changes in the test responses was assessed using a one-way ANOVA followed by LSD test (Analyze-it, Leeds, UK); differences were considered significant at P 0.05. |

細(xì)胞培養(yǎng)和細(xì)胞毒性檢測: 取增長期的 H4IIE 的鼠肝癌細(xì)胞,用DMEM培養(yǎng)基培養(yǎng)(含4.5 g/L 的葡萄糖,2 mmol/L的谷酰胺,100單位的青霉素鈉,100mg/ml的鏈霉素以及10%的胎牛血清),于37 °C, 5% CO2的培養(yǎng)箱中孵育。用MTT法測定分離的化合物對細(xì)胞活力的影響。 先將細(xì)胞鋪于96孔板中,10000個(gè)/孔,24小時(shí)后,加入不同濃度的化合物,繼續(xù)孵育24h。加入0.7mg/ml的MTT,換液,細(xì)胞于培養(yǎng)條件下繼續(xù)孵育3h,加入50% 乙醇/49% 水/1% HOAc溶解(形成的甲瓚顆粒)。于560nm處檢測,MTT降低的濃度作為細(xì)胞活力的標(biāo)志,數(shù)據(jù)是至少三次獨(dú)立試驗(yàn)的統(tǒng)計(jì)結(jié)果,采用ANOV方差檢驗(yàn)來分析數(shù)據(jù)間是否具有統(tǒng)計(jì)學(xué)差異。p值小于0.05被定義為有顯著性。 英語不太好,有些事意譯,你湊合看吧。你要是需要MTT法檢測細(xì)胞增殖之類的方法,我可以給你 |
