Ren TJ, Zhang XX, Li X, Chen HX. Isoforms analysis of recombinant human erythropoietin by polarity-reversed capillary isoelectric focusing. Electrophoresis 2020; 41:2055-2061. [PMID: 32841408 DOI: 10.1002/elps.202000165] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Revised: 08/05/2020] [Accepted: 08/10/2020] [Indexed: 12/28/2022]
Abstract
Recombinant human erythropoietin (rhuEPO) has been extensively used as a pharmaceutical product for treating anemia in the clinic. Glycosylation of rhuEPO was crucial for affecting biological activity, immunogenicity, and pharmacokinetics. Because of the heterogeneity of glycan, the structure of rhuEPO was complex with several isoforms. Characterization of isoforms was important for quality control of rhuEPO. Here, an improved cIEF method has been established and validated. A polarity-reversed focusing step was used by reversing both the polarity of the voltage and the catholyte and anolyte vials. A weak base (100 mM ammonium hydroxide solution) was used as a chemical mobilizer to make the acidic bands mobilize stably to the detection window. Compared with CZE method in European Pharmacopoeia, the numbers of isoforms and their peak area percentage were highly consistent. Better reproducibility and higher resolution have been obtained by the improved cIEF method. Moreover, in improved cIEF method, the isoelectric points (pI) of each isoform can be calculated and used for identification. It was also the first time that the cIEF method was fully validated for rhuEPO analysis according to the International Conference on Harmonization (ICH) guidelines.

Acidic hydrolysate fingerprints based on HILIC-ELSD/MS combined with multivariate analysis for investigating the quality of Ganoderma lucidum polysaccharides. Int J Biol Macromol 2020; 163:476-484. [PMID: 32593759 DOI: 10.1016/j.ijbiomac.2020.06.206] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Revised: 06/04/2020] [Accepted: 06/22/2020] [Indexed: 02/06/2023]
Abstract
In this preliminary study, the acidic hydrolysate fingerprints of polysaccharides based on hydrophilic-interaction chromatography-evaporative light scattering detection-electrospray time-of-flight mass spectrometry (HILIC-ELSD/ESI-TOF/MS) combined with multivariate statistical analysis was developed and applied to investigate the quality of Ganoderma lucidum from different regions. Projection-to-latent-structure discrimination analysis (PLS-DA) could distinguish samples of Zhejiang regions from those of other regions. Orthogonal-projection-to-latent-structure discrimination analysis (OPLS-DA) provided clear discrimination between G. lucidum samples cultivated in Zhejiang and that from other regions, in which Polysaccharides and D-galactose could be considered as candidate biomarkers. In addition, the intraspecific differentiation of G. lucidum was preliminarily investigated with samples from Shaanxi region. They were classified into four groups by PCA and PLS-DA, in which L-rhamnose, D-xylose, L-arabinose, and mannose were considered as potential chemical markers. These preliminary results contributed to our understanding of the variance of polysaccharides in Ganoderma spp. from different geographic origins and the intraspecific differentiation from the same region, which suggest great potential in the quality control of Ganoderma spp.

Abstract
This review covers the basics and some applications of methodologies for the analysis of glycoprotein glycans. Analytical techniques used for glycoprotein glycans, including liquid chromatography (LC), capillary electrophoresis (CE), mass spectrometry (MS), and high-throughput analytical methods based on microfluidics, were described to supply the essentials about biopharmaceutical and biomarker glycoproteins. We will also describe the MS analysis of glycoproteins and glycopeptides as well as the chemical and enzymatic releasing methods of glycans from glycoproteins and the chemical reactions used for the derivatization of glycans. We hope the techniques have accommodated most of the requests from glycoproteomics researchers.

Abstract
This chapter reports an overview of the recent advances in the analysis of mono- and oligosaccharides by capillary electrophoresis (CE); furthermore, relevant reviews and research articles recently published in the field are tabulated. Additionally, pretreatments and procedures applied to uncharged and acidic carbohydrates (i.e., monosaccharides and lower oligosaccharides carrying carboxylate, sulfate, or phosphate groups) are described.Representative examples of such procedures are reported in detail, upon describing robust methodologies for the study of (1) neutral oligosaccharides derivatized by reductive amination and by formation of glycosylamines; (2) sialic acid derivatized with 2-aminoacridone, released from human serum immunoglobulin G; (3) anomeric couples of neutral glycosides separated using borate-based buffers; (4) unsaturated, underivatized oligosaccharides from lyase-treated alginate.

Abstract
After 20 years of development, evaporative light-scattering detection (ELSD) has become the mainstream choice for the detection of various classes of natural products. ELSD continues to grow in popularity as a "quasi-universal" technique because of the specificity of the detection method, which is based on the scattering of laser light from nonvolatile analyte particles. It represents an attractive alternative compared to other types of detection, such as refractive index detection and/or ultraviolet detection. This review presents issues concerned with the separation of carbohydrates in plant materials by HPLC and ELSD, as well as the advantages and limitations relating to the ELSD method. Additionally, an overview of possible ELSD applications in the analysis of carbohydrates in natural products is presented.

Abstract
This review summarizes the analytical advances made during the last several years in the structural and quantitative determinations of glycoproteins in complex biological mixtures. The main analytical techniques used in the fields of glycomics and glycoproteomics involve different modes of mass spectrometry and their combinations with capillary separation methods such as microcolumn liquid chromatography and capillary electrophoresis. The need for high-sensitivity measurements have been emphasized in the oligosaccharide profiling used in the field of biomarker discovery through MALDI mass spectrometry. High-sensitivity profiling of both glycans and glycopeptides from biological fluids and tissue extracts has been aided significantly through lectin preconcentration and the uses of affinity chromatography.

Abstract
The field of glycomics has recently advanced in response to the urgent need for structural characterization and quantification of complex carbohydrates in biologically and medically important applications. The recent success of analytical glycobiology at high sensitivity reflects numerous advances in biomolecular mass spectrometry and its instrumentation, capillary and microchip separation techniques, and microchemical manipulations of carbohydrate reactivity. The multimethodological approach appears to be necessary to gain an in-depth understanding of very complex glycomes in different biological systems.

Abstract
Glycosylation is the most complex form of protein PTMs. Affected proteins may carry dozens of glycosylation sites with tens to hundreds of glycan residues attached to every site. Glycosylated proteins have many important functions in biology, from cellular to organismal levels, being involved in cell-cell signaling, cell adhesion, immune response, host-pathogen interactions, and development and growth. Glycosylation, however, expands the biological functional diversity of proteins at the expense of a tremendous increase in structural heterogeneity. Aberrant glycosylation of cell surface proteins, as well as their detectable fingerprint in plasma samples, has been associated with cancer, inflammatory and degenerative diseases, and congenital disorders of glycosylation. Therefore, there are on-going efforts directed toward developing new technologies and approaches for glycan sequencing and high-throughput analysis of glycosylated proteins in complex samples with simultaneous characterization of both the protein and glycan moieties. This work is aimed primarily at pinpointing the challenges associated with the large-scale analysis of glycoproteins and the latest developments in glycoproteomic research, with focus on recent advancements (2011-2012) in microcolumn separations and MS detection.
