Alternatives and Modern Approaches Although the ninhydrin method is widely used, other techniques can provide greater accuracy or sensitivity: l High-Performance Liquid Chromatography (HPLC): Separates and quantifies free amino acids with excellent precision. ...
Antibody-Drug Conjugates (ADCs) represent a groundbreaking advancement in targeted cancer therapy, combining the specificity of antibodies with the potency of cytotoxic drugs. The development and production of ADCs are complex processes that require a deep understanding of both biology and chemistry, alongside cutting-edge technology. This article delves into the intricacies of ADC development ...
Size distribution analysis of microsized water particle mist generated from an odor control technology showed the major- ity of particles to be in the low micron range. The indirect detection and determination of hydroxyl radicals generated by their reaction with benzene to produce phenol was performed through UV-Vis spectrophotometry (UV-Vis) and high perfor- mance liquid ...
Chromatographic methods Liquid chromatography (LC) and gas chromatography (GC) are powerful separation techniques widely used for anthocyanin analysis. High-performance liquid chromatography (HPLC) coupled with UV-visible or diode array detection allows for the separation and quantification of anthocyanins based on their retention times and absorbance spectra. ...
Mass Spectrometry DetectionDeuterated peptides are separated by low-temperature HPLC/UPLC, and then entered into MS analysis. Based on the mass difference between hydrogen and deuterium, MS can monitor HDX changes by measuring the mass center displacement of peptides.5. ...
These techniques can not only determine the molecular weight of small molecule peptides but also identify the sequence of peptide segments through database search and algorithm analysis.2. High-Performance Liquid Chromatography (HPLC)HPLC is a separation analysis technique that can be used for the purification and identification ...
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 ...
It is often used for peptide mass spectrometry analysis, especially in protein identification and proteomics research. ...
The commonly used HPLC modes in glycosylation analysis include reverse phase high performance liquid chromatography (RP-HPLC), Ion exchange chromatography (IEC), and hydrophilic interaction chromatography (HILIC). HPLC can provide information on glycosylation heterogeneity, such as the length and branching of glycan chains, and ...
The mass spectrometry analysis has become the mainstream method for determining the amino acid sequence of proteins. ...
Trypsin Digestion The lysed antibody is treated with trypsin or other specific proteases to produce smaller peptides that can undergo sequence analysis. Peptide Purification and Separation The peptides obtained are further purified and separated by high-performance liquid chromatography (HPLC) or similar techniques. Mass Spectrometry Analysis ...
High-performance liquid chromatography (HPLC) is a popular method for vitamin analysis, offering high precision and sensitivity. ...

With the development of high-resolution mass spectrometry (HMS) and its instruments, the qualitative and quantitative analysis of compound quality determination has received more and more attention and been widely used by researchers. ...
Analysis of Chiral Drugs: Due to the same physical and chemical properties of drug enantiomers, it is difficult to separate them by conventional HPLC methods. ...
APPLICATION Most ethanol test kits for on-site analysis of gasoline use densitometry measurement, which are rudimentary disposable test tubes that measure ethanol by the difference in density between ethanol and water. ...
There has been a growing national interest in the effective analysis of THC vape oils. One of the challenges is that vape oil comes with a complex solvent that contains a variety of volatile and semi-volatile ingredients. Before analysis via GC or HPLC, the sample needs to be either extracted or diluted before analysis, to avoid ...
