When added with cytochrome c, Xenopus laevis egg extract XS-150 can induce exogenous nuclei undergoing apoptosis. Apoptosis specific DNase XAD was activated during this process, and cut chromatin between nucleosome, l...
To study the mechanism of plant apoptosis, a cell-free system has been developed using the extracts prepared from tobacco cells that become committed to apoptosis induced by heat shock treatment. Tobacco nuclei have d...
The apoptosis of carrot nuclei induced in cytosol of carrot cells by cytochrome c is reported. This kind of cell-free apoptosis system of plant, CS-100, is an efficient In vitro inducing system. Several typical charac...
A cell-free apoptosis system was established by adding dATP and cytochrome c to Xenopus laevis egg extracts S-150. Accompanied by an incubation process, an apoptosis-specific DNase was activated in egg extracts which ...
Studies so far indicate that many processes in the interactions between biomacromole-cules are accompanied by a change in occupied volume. For instance, the association ofprotein subunits into oligomer and the formati...

1 Introduction Nuclear assembly occurs universally in cell life, such as postmitotic or postmeiotic nuclear assembly. It is a good model for studying the organization and function of nucleus. The organism or even sing...
In cold surroundings, in both plants and animals (the class of fish, amphibian, mammal, etc.) tissue cells may appear many special anti-freeze proteins or cold adaptation-associated proteins for existence and developm...

Ⅰ. INTRODUCTIONNuclear reconstitution (nuclear assembly )was reported by several laboratories in recent years and regarded as an important advance in cell biology. In vitro nuclear assembly system provides a good mod...
Extracts with nitrogenase activity have been prepared from 20 different organism,since J. E. Carnahan et al. demonstrated nitrogeuase activity in the crude extract from Clostridium pasteurianum in 1960. The properties...
