1.After etoposide exposure,the ladder DNA produced by the bcl-2 transfected CEM cells reduced by approximately 20% as compared with control(P<0.05).
2.a diffraction grating consisting of a pile of plates of equal thickness arranged stepwise with a constant offset.
3.Synthesis, Structure and Magnetic Property of a Two-dimensionalStair-like Framework: [Ni(μ_(1,5)-dca)_2(en)]_n
4.Apoptosis was determined by FACS analysis and DNA ladder.
5.Study on Preparation, Phase Analysis and Physical Properties of the Spin-1/2 Ladder Compound Sr_(14-x)Ca_xCu_(24)O_(41)
6.The monomer ( about 350 bp )of the Hind Ⅲ satellite DNA was isolated from the genomic DNA, and named as CDa(HindⅢ)-1. The Southern Blot experiments with this fragment as a probe indicates that the Hind Ⅲ Satellite DNA consists of tandemly repeated monomers.
7.Trichosanthin (TCS), an eukaryotic ribo-some-inactivating protein isolated from the root tuber of Trichosanthes plant, has various biological activities including abortion induction, anti-tumor, and anti-HIV. In this study, cultured human leukemia K562 cells treated with trichosan-thin were examined.
8.The clear DNA ladder were observed in the DNA gel electrophoresis and the apoptotic PAa/M_~2-1 cell were also observed in cultural cell by using the TEM.
9.The HCECs underwent much remarkable apoptosis when treated with 800μmol/L H2O2 for 10h, and an obvious DNA ladder was found in electrophoresis.
10.Methods Quantitative measurement of apoptosis and detection of “DNA ladders” were performed by FCM and agarose electrophoresis respectively in BGM cells and McCoy cells infected with Chlamydia trachomatis at different time (36 h,48 h,60 h). Results DNA ladder were observed in BGM cells and McCoy cells from 48 h to 60 h after infected with Chlamydia trachomatis K serotype.
