  3. Structural changes of solvent-vapor-treated SF nanofibers were studied using time-resolved IR spectroscopy. Conformational transitions from random coils to beta-sheets depended on the solvent vapor used. Treatment temperatures affected transition rates.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
