Here, the molecular sizes of N2 and water were approximately 0.4 and 0.3 nm, respectively.
The separation of the components of a mixture by gel chromatography is based on the differences in the molecular sizes of the components.
It should be noted that preparation of an oligosaccharide or polysaccharide usually results in a range of molecular sizes of the desired molecule.
This relationship is derived by assuming ideality of both phases, energetic heterogeneity of the solid and different molecular sizes of solutes.
Both linear and branched-chain PEG reagents with molecular sizes of up to 40 kDa have been used with a variety of different PEG derivatives with different linker chemistries.
The noise-induced membrane damage was assessed functionally, using membrane tracers with graded molecular sizes (propidium iodide and FITC-dextrans with molecular sizes of 3, 40, 500, and 2000 kDa), and morphologically, using DiO staining and semithin sections.
Sodium dodecyl sulfate-polyacrylamide gel electrophoresis revealed two major subunits with apparent molecular sizes of 72 kDa and 32 kDa.
The molecular sizes of protein (a) and (b) were estimated to be about 80,000 and 65,000, respectively.
The scale bars were 2 μm for a c, 200 nm for d f, and 100 nm for g i Fig. 4 Molecular sizes of E. coli genotypes.
The molecular sizes of the acid-soluble constituents dissociated by concentrated urea treatment were similar to those dissociated by preparative PAGE in the presence of concentrated urea [7].
It can be seen that while the molecular sizes of the six HAs covered similar ranges, definite differences existed in their distributions.
