The Sanger-based sequencing reads were assembled onto this backbone.
The UV-Vis spectral properties of the polymer solution are dependent upon the backbone conjugation length, which describes the length over which the π-electrons are delocalised.
The selective insertion of pseudo-proline (ΨPro) systems featuring different 2-C-substituents at the oxazolidine ring exerts dramatic effects upon the backbone conformation as demonstrated by NMR analysis.
However, those were strongly dependent upon the polyimide backbone chemistry and precursor origin.
The measured Tis are in the range 198.1 235.4°C, depending upon the precursor backbone structure as well as the history of sample preparation.
The measured Tgs are in the range 179.2 235.4°C, depending upon the precursor backbone structure as well as the history of sample preparation: these Tgs are very close to the imidization temperatures (Tis), causing difficulties in the Tg measurements.
The precursors and their alternating copolyimides in films have exhibited structural orders that are estimated to have a dimension of 15 42 Å (along the chain axis) and 8 16 Å (along the lateral direction), depending upon the polymer backbone chemistry.
Upon oxidation, the backbone amide of the coordinating Cys26 is deprotonated by the nearby glutamic carboxylate and replaces the bridging Cys25, analogous to the P cluster in nitrogenases.
Most schools frown upon this.
"This is a backbone," he wrote.
