End-synapsis Assay 末端染色体结合试验 作者:Jessica Cottarel and Patrick Calsou日期:09/20/2013,浏览量:7343,Q&A: 0
Many environmental agents induce double-strand breaks (DSBs) in DNA. Unrepaired or improperly repaired DSBs can lead to cell death or cancer. Nonhomologous end joining is the primary DNA double-strand break repair pathway in eukaryotes. During NHEJ pathway, several proteins recognize and bind DNA ends, bring the ends in a synaptic complex and, ...

Choline Uptake Assay in Bacterial Cells 细菌细胞中的胆碱摄取分析 作者:Lucas Bukata, Claudia K. Herrmann and Diego J. Comerci日期:09/20/2013,浏览量:9100,Q&A: 0
Choline is a methylated nitrogen compound that is widespread in nature. It is a precursor of several metabolites that perform numerous biological functions and it is predominantly used for the synthesis of essential lipid components of the cell membranes. Since there is no evidence that prokariotes can synthesize choline de novo and ...

Isolating RNA from the Soil 从土壤中分离RNA 作者:Jacqueline M Chaparro and Jorge M Vivanco日期:09/20/2013,浏览量:10123,Q&A: 0
Next generation sequencing has allowed for the analysis and ability to identify the microbial communities present in the environment. While DNA extraction from environments (such as soil) have provided a wealth of knowledge regarding microbial communities there are drawbacks that one encounters when using DNA as opposed to RNA. RNA allows for the ...

Measurement of Extracellular Ca2+ Influx and Intracellular H+ Efflux in Response to Glycerol and PEG6000 Treatments 测定响应甘油和PEG6000的胞外Ca2+流入量和胞内 H+流出量 作者:Tao Li and Baodong Chen日期:09/20/2013,浏览量:8364,Q&A: 0
The characteristics of Ca2+ and H+ fluxes may reflect the activities of aquaporins, as the up-regulation of aquaporin activities is directly associated with the decrease in cytoplasmic H+ concentration and increase in cytoplasmic Ca2+ concentration. The higher aquaporin activities can protect cells ...
