4.2.1藥物對(duì)細(xì)胞的毒性測(cè)定 用胰酶將生長良好的HEp-2細(xì)胞分散成單個(gè)細(xì)胞懸液接種于96孔板。置37 ℃,5% CO2培養(yǎng)箱中培養(yǎng)24 h。待細(xì)胞長成單層后,棄培養(yǎng)液上清,加入不同濃度的含藥維持液,每一藥物濃度重復(fù)4孔,同時(shí)設(shè)正常細(xì)胞對(duì)照。每天于倒置顯微鏡下觀察細(xì)胞變化,48 h后用MTT法檢測(cè)細(xì)胞存活率。實(shí)驗(yàn)重復(fù)3次。以Probit回歸方法計(jì)算藥物半數(shù)毒性濃度(CC50),并根據(jù)細(xì)胞存活率找出藥物對(duì)細(xì)胞的最大無毒濃度范圍。 |

修飾后的 4.2.1 Cytotoxicity assay: HEp-2 cells grown in exponential phase were trypsinized and dispersed into single cell suspension and seeded into 96-well plates, cultured for 24 hrs at 37 ℃,5% CO2. Next day, the culture medium was removed and replaced with medium containing various concentrations of the drug in quadruplicates with medium alone as the control group. Cells were monitored daily under an invert light microscope for obvious morphological changes. 48hr later, MTT assays were conducted to determine cell viability. Each experiment was repeated 3 times. By using probability unit method, the half maximal toxicity concentrations (CC50) were estimated, furthermore, based on cell viability results, the maximal non-toxic dose ranges were identified. |
