Solution properties of fractions of a perfluoropolyether copolymer (PFPE Z) having the structure CF3 OC2 F4 p(OCF2)qOCF3have been studied in two solvents, 1,1,2-trichloro-1,2,2-trifluoroethane (CFC 113) and perfluoroheptane, over a large molecular weight range.
In contrast, native continuous elution PAGE provides high-resolution separation of GAG-derived oligosaccharides over a large molecular weight range, and the gel-eluted oligosaccharides are amenable to structural characterization [ 82].
Transcutaneous vaccination via laser-generated micropores requires the application of large molecular weight substances ranging from several kDa (small proteins) to antigen complexes in the nanometer to micrometer range, such as liposomes, nanoparticles and microparticles or viral particles.
The order in which the hydrocarbon compounds are oxidized depends on a variety of factors, but in general small molecules up to C20 are consumed before large ones, and within the same molecular weight range the order is usually n-paraffins first, followed by iso-paraffins, naphthenes and aromatics; single-ring naphthenes and aromatics are attacked before iso-prenoids, steranes and triterpenes.
Of the lectins that were screened, AAL, jacalin (JAC) and wheat germ agglutinin (WGA) reacted with the largest number of bands spanning the greatest molecular weight range (compare Fig. 1b with Additional file 1: Figure S1).
SEC was performed at room temperature using five columns (PLgel 10 μm 10, 10, 10, and 106 Å, plus a larger 107 Å Shodex column) to cover the broad molecular weight range of the carbanilated celluloses.
Biologics comprise a broad range of molecules that are typically large molecular weight drugs, which include peptides, polypeptides, proteins, antibodies and enzymes.
Inhibitory strength eluted over a large volume, indicating that the mixture of different species spanning the molecular weight range of approximately 0.5 – 10 kDa is responsible for the inhibition.
The symptoms of envenomation produced by a diverse array of catfish species' venoms are very similar and a large number of putative toxins appear to fall within a well-defined molecular weight range.
However, our results are not unexpected given the large range of protein complex sizes that exist within the membranes of mitochondria and are consistent with the broad molecular weight range of extracted complexes detected by BN-PAGE.
This extended the molecular weight range of chromatography to polypeptides, proteins, and high-molecular-weight polymers.
