Biosimilar, biobetter, and next generation antibody characterization by mass spectrometry.
This Feature will introduce the strategies of therapeutic antibodies (mAbs) in-depth characterization by mass spectrometry (MS) and discuss analytical comparison of biosimilar to originator mAbs, with the cases of trastuzumab and cetuximab. In addition, the structural and functional insights gained both by state-of-the art and emerging MS methods used for biobetters and next generation antibodi...
متن کاملProduction and Characterization of a Monoclonal Antibody Neutralizing Poliovirus Type 2
Monoclonal Antibodies (mAbs) are used for biomedical research, diagnosis, treatment, production, and the quality control of biological products. mAbs are also very helpful in poliovirus research studies because it is still one of the major public health problems in developing countries. The main objective of this study was the production of mAbs against Poliovirus Type 2 (PV2) to be prepared an...
متن کاملIn-depth sphingomyelin characterization using electron impact excitation of ions from organics and mass spectrometry.
Electron impact excitation of ions from organics (EIEIO), also referred to as electron-induced dissociation, was applied to singly charged SM molecular species in the gas phase. Using ESI and a quadrupole TOF mass spectrometer equipped with an electron-ion reaction device, we found that SMs fragmented sufficiently to identify their lipid class, acyl group structure, and the location of double b...
متن کاملCharacterization of uremic "middle molecular" fractions by gas chromatography, mass spectrometry, isotachophoresis, and liquid chromatography.
Uremic ultrafiltrates (and normal serum, for comparison) were fractionated by means of gel filtration. The collected fractions were further investigated by combined analytical techniques: "high-performance" liquid chromatography, gas chromatography, mass spectrometry, and isotachophoresis. Ultrafiltrate fractions in the so-called middle molecular mass region (Mr 500-2000) contained a considerab...
متن کاملIn-Depth Characterization of Protein Disulfide Bonds by Online Liquid Chromatography-Electrochemistry-Mass Spectrometry
Disulfide bonds are an important class of protein post-translational modifications, yet this structurally crucial modification type is commonly overlooked in mass spectrometry (MS)-based proteomics approaches. Recently, the benefits of online electrochemistry-assisted reduction of protein S-S bonds prior to MS analysis were exemplified by successful characterization of disulfide bonds in peptid...
