【摘要】:研究不同浓度的碘化丙啶(PI)染色对细胞周期分布的影响。293T细胞经0、2、4、6Gy的X射线照射后,用浓度分别为5、10、20、50μg/ml的PI染色后,流式细胞仪检测细胞周期的分布情况。0、2、4、6Gy时,不同浓度PI染色时G1/G0期的比例变化如下:(35.90±0.17)至(37.65±0.42),(18.05±0.40)至(19.08±2.01),(4.24±1.31)至(5.89±1.08),(2.88±0.16)至(4.04±1.06),G2/M期的比例变化如下:(13.36±0.36)至(15.39±0.33),(54.56±0.34)至(58.98±1.46),(83.92±4.50)至(84.80±1.43),(92.29±1.56)至(92.89±1.49);S期的比例变化如下:(45.63±0.97)至(49.74±0.16),(22.45±0.35)至(27.04±0.36),(10.05±0.79)至(11.29±0.11),(3.71±1.06)至(4.99±1.01)。在同一照射剂量下,不管是G1/G0期、S期还是G2/M期,不同浓度PI染色对细胞周期分布没有明显差异(P0.05);但不管5、10、20μg/ml还是50μg/ml的PI染色,随着照射剂量的增加,G2/M期细胞比例明显增加(P0.01)。随着照射剂量的增加,G2/M期细胞比例明显增加;但对于同一照射剂量,不同浓度PI染色对细胞周期分布没有明显差异,做周期分布实验时选择5μg/ml的PI染色即可。
