Size and Shape of Protein Molecules at the Nanometer Level Determined by Sedimentation, Gel Filtration, and Electron Microscopy

is also frequently useful: M (Da) = 825 V (nm3 ). What we really want is a physically intuitive parameter for the size of the protein. If we assume the protein has the simplest shape, a sphere, we can calculate its radius. We will refer to this as R min

distinct subpopulations of cells on the basis of these measured characteristics, usually by electrostatic deflection. This separation technology is called electronic cell sorting.Flow cytometry has two general applications—quantitative analysis and cell

A Method for StructureActivity Analysis of Quorum-Sensing Signaling Peptides from Naturally Transformable Streptococci

Chemical Synthesis of Signaling Peptides Efficient structural characterization of signaling peptides by CD and NMR requires purified (≥95% purity) and soluble peptides. In our study, all the peptides were commercially synthesized and purified
