Abstract
An increased focus on characterizing the structural heterogeneity of carbohydrates has been driven by their many significant roles in extant life and potential roles in chemical evolution and the origin of life. In this work, multiplexed drift tube ion mobility-Orbitrap mass spectrometry methods were developed to analyze mixtures of disaccharides modified with noncovalent shift reagents. Since traditional coupling of atmospheric pressure drift tube ion mobility cells with Orbitrap mass analyzers suffers from low duty cycles (<0.1%), a frequency modulation scheme was applied to improve the signal-to-noise ratios (SNR). Several parameters such as the resolution setting and maximum injection time of the Orbitrap analyzer and the magnitude and duration of the frequency sweep were investigated for their impact on the sensitivity gains and resolution of disaccharide-shift reagent adducts. The sweep time and disaccharide concentration had a positive correlation with SNR. The magnitude of the frequency sweep had a negative correlation with SNR. However, increasing the frequency sweep improved the resolution of mixtures of disaccharide analytes. Application of frequency-modulated ion mobility-Orbitrap mass spectrometry to four noncovalently modified glucose dimers allowed for the differentiation of three out of these four analytes.

Abstract
The effect of polymer charge density on protein selectivity in the presence of carboxylated polysaccharides (CPS) and sulfated polysaccharides (SPS) was investigated for Kunitz trypsin inhibitor/Bowman-Birk protease inhibitor (KTI/BBI, KBM). To determine the conditions for coacervation or precipitation as a function of polymer charge densities, turbidimetric titrations and Tricine-SDS-PAGE were used. Polymer charge density as well as chain flexibility greatly influenced the strength of interactions and protein recovery. Although charge compensation must occur for CPS-KBM complexes, SPS-KBM systems did not require conservation of charge neutrality. Despite their similar isoelectric points, KTI bound preferentially to CPS and SPS due to its higher affinity compared to BBI. Complexation of KBM with the polysaccharide with the lowest charge density, arabic gum, expectedly cannot realize the purification of BBI under conditions where binding to more highly charged polysaccharides occurs. This work will be beneficial to selective purification of target proteins through control of protein-polysaccharide complexation.

Abstract
In this work, the optimization process of interpolymeric complexes formation between lactalbumin and the polysaccharides xanthan gum and pectin was studied in order to define the optimum conditions for the complexes formation. For the experimental design, response surface methodology (RSM) for three independent variables was used. The optimum conditions for the complexes formation between lactalbumin and xanthan gum were: pH 6.6, NaCl concentration of 0.6 mol/L and xanthan gum concentration 0.083% w/v. And for the complexes formed between pectin and lactalbumin the conditions were: pH 6.6, NaCl concentration of 0.25 mol/L and pectin concentration of 0.113% w/v. The best fitted model for the experimental data was that corresponding to the complex xanthan gum-lactalbumin, whose coefficient of determination (R²) was 0.97.
