The use of DAPI (4′, 6-diamidino-2-phenylindole) as a DNA specific fluoresoent probe to cells or protoplasts of higher plants was limited by its difficulty of being transported across membrane.

The use of DAPI (4′, 6-diamidino-2-phenylindole) as a DNA specific fluoresoent probe to cells or protoplasts of higher plants was limited by its difficulty of being transported across membrane. We, however, have rendered DAPI to permeate in protoplasts from the 展开更多

作者 唐孝威 张长春 《Chinese Science Bulletin》 SCIE EI CAS 1982年第3期345-,共1页
Two photons each with 511 KeV are produced in the annihilation of electron-positron at1S0 state, The conservation of angular momentum requires that these two photons should have the same sense of circular polarization... Two photons each with 511 KeV are produced in the annihilation of electron-positron at1S0 state, The conservation of angular momentum requires that these two photons should have the same sense of circular polarization, that is, they must be either 'left-left’ or 'right-right' photon pairs. From the correlation of the 展开更多

Phlegmariuine is a new compound isolated from the whole plant part of Phlegma-riurus fordii (Baker)Ching of Lycopodiaceae, from Jiangxi and Fujian provinces with a molecular formula C16H23O2N. It was recorded that the alkaloids isolated out from the whole plant such as L. Cernuum L. and L. Complanatum L. are, in terms of traditional Chinese medical science, effective to expel rheumatic fever, to clear 展开更多
