Stretched Poly(acrylonitrile) as a Scalable Alignment Medium for DMSO

摘要

We have shown that stretched poly(acrylonitrile)/ DMSO gels are very useful alignment media for the measurement of anisotropic NMR parameters. The few broad NMR signals resulting from the polymer backbone can be reduced by relaxation filters, and small detected impurities can be neglected. As the polymer is freely scalable, uncharged, and compatible with peptides and other molecular classes, it is widely applicable and even complementary to existing alignment media.
