M any types of free-living bacteria communicate with one another by chemical signals, thereby coordinating metabolic activities and developmental processes. For instance, starved cells of the myxobacterium Myxococcus xanthus release the A signal, a mixture of six amino acids, to promote aggregation, the first step in the development of a fruiting body. Escherichia coli cells coordinate their mo...

Background: Electroporation is a valuable tool for small interfering RNA (siRNA) delivery into cells because it efficiently transforms a wide variety of cell types. Since electroporation condition for each cell type must be determined experimentally, this study presents an optimal electroporation strategy to reproducibly and efficiently transfect MDA-MB 468 human breast cancer cell with siRNA. ...
