The one-dimensional (1D) diffusion edited proton NMR method, Protein Fingerprint by Lineshape Enhancement (PROFILE) has been demonstrated to be suitable for higher order structure (HOS) characterization of protein therapeutics including monoclonal antibodies. Recent reports in the literature have demonstrated its advantages for HOS characterization over traditional methods such as circular dichroism and Fourier-transform infrared spectroscopy. Previously, we have demonstrated that the PROFILE...

Principal component analysis for automated classification of 2D spectra and interferograms of protein therapeutics: influence of noise, reconstruction details, and data preparation
Principal component analysis for automated classification of 2D spectra and interferograms of protein therapeutics: influence of noise, reconstruction details, and data preparation
Abstract
Protein therapeutics have numerous critical quality attributes (CQA) that must be evaluated to ensure safety and efficacy, including the requirement to adopt and retain the correct three-dimensional fold without forming unintended aggregates. Therefore, the ability to monitor protein higher order structure (HOS) can be valuable throughout the lifecycle of a protein...

[U. of Ottawa NMR Facility Blog] 1H T1? Edited 13C CPMAS Spectra - Pharmaceutical Analysis
1H T1? Edited 13C CPMAS Spectra - Pharmaceutical Analysis
Active pharmaceutical ingredients (API's) are often mixed with other compounds (excipients) used to dilute, stabilize, sweeten, color, flavour, bind, coat (etc...) the medication. Often the API is a crystalline compound while the excipients are noncrystalline or amorphous. When analyzing pharmaceutical pills by solid-state 13C CPMAS NMR, one often wants to observe the active crystalline API and not the amorphous non-active excipients. This can sometimes be accomplished by collecting spectra with differing recycle delays, as the...

NMR-based fragment screening and lead discovery accelerated by principal component analysis
NMR-based fragment screening and lead discovery accelerated by principal component analysis
Abstract
Protein-based NMR spectroscopy has proven to be a very robust method for finding fragment leads to protein targets. However, one limitation of protein-based NMR is that the data acquisition and analysis can be time consuming. In order to streamline the scoring of protein-based NMR fragment screening data and the determination of ligand affinities using 2D NMR experiments we have developed a data analysis workflow based on principal component...

Abstract
Defining the RNA target selectivity of the proteins regulating mRNA metabolism is a key issue in RNA biology. Here we present a novel use of principal component analysis (PCA) to extract the RNA sequence preference of RNA binding...
