Mass SpectrometryThis detects phosphorylated peptides in protein samples through mass spectrometry technology, providing precise locations and quantitative information about phosphorylation sites.3. ImmunoprecipitationThis uses phosphorylation-specific antibodies to precipitate phosphorylated proteins, followed by detection through western blot or mass ...
These forms of glycosylation affect protein folding, stability, and distribution.Methods and Techniques for Glycosylation Site DetectionTraditional glycosylation site detection methods include mass spectrometry analysis and Western blotting. Mass spectrometry can accurately identify glycosylation sites, while Western blotting is used to detect ...
Mass Spectrometry TechnologyMass spectrometry technology directly measures the mass and structure of T cell receptor proteins to identify differences among different T cell clones. ...
Finally, the presence of ubiquitinated proteins is determined by detecting the labeled antibodies.Mass SpectrometryMass spectrometry can provide more detailed and accurate information, including ubiquitination sites and types of ubiquitin chains. Firstly, the protein sample needs to be enzymatically digested, and then the ubiquitination site is analyzed by liquid ...

During the production process, the content and type of monosaccharides may be affected by many factors, such as the type of host cell, culture conditions, protein folding, and glycan assembly, etc. Therefore, detailed analysis and control of the monosaccharide content and types in recombinant protein vaccines are very important.To analyze the content and types of monosaccharides ...
Immunoblot AnalysisPerform immunoblotting (Western Blot) analysis using antibodies against ubiquitin to detect whether Tau protein is ubiquitinated.5. Mass Spectrometry AnalysisFor accurate identification of ubiquitin sites on Tau protein, further mass spectrometry analysis can be performed.6. Data AnalysisAnalyze the ...
Below are some common biological methods:1. Mass Spectrometry AnalysisMass spectrometry is a powerful technique. In collagen peptide research, mass spectrometry often uses a mass spectrometer to measure the mass-to-charge ratio (m/z) of peptide segments, and then calculates the average molecular weight based on the mass ...
DIA technology has a wide range of applications in biomedical research, disease biomarker discovery, and drug development.DIA Proteomics SequencingDIA technology systematically scans the entire mass range during mass spectrometry analysis, rather than analyzing only a few preselected ions. ...
Karyotype analysis refers to the pairing and grouping of chromosomes to reveal whether the organism accords with the inherent chromosomal characteristics, to determine if the organism has chromosomal abnormalities. Karyotype analysis can detect whether there are abnormalities in chromatin length, centromere position, the ratio of long and short arms, and the ...
Characterization of mAb intermediates includes primary structure (amino acid sequence, N-terminal/C-terminal sequence analysis, peptide map), secondary or tertiary structure, protein fragments/aggregates, and charge variants, glycosylation modification, post-translational modification, target binding properties and biological activity, etc. ...
In addition, due to the synthesis route and the storage stability issues that have been neglected, The GPC and macromolecular mass spectrometry analysis results of commercially sold functionalized polyethylene glycol (PEG-NH2) are very unsatisfactory. ...
