RP-HPLC estimation of ramipril and telmisartan in tablets

open access: yesIndian Journal of Pharmaceutical Sciences, 2009
A rapid high performance liquid chromatographic method has been developed and validated for the estimation of ramipril and telmisartan simultaneously in combined dosage form. A Genesis C18 column having dimensions of 4.6x250 mm and particle size of 5 mum in isocratic mode, with mobile phase containing a mixture of 0.01 M potassium dihydrogen phosphate ...

Chemical Proteomics Reveals Protein Tyrosination Extends Beyond the Alpha‐Tubulins in Human Cells**

open access: yesChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Protein post‐translational modifications allow cells to swiftly adjust activity and localization of proteins. Here, we developed a chemical proteomic approach to determine a protein tyrosination status using an O‐propargyl tyrosine probe. We show that tyrosination modifies previously described alpha‐tubulins with ‐EEY C‐terminal sequence together with ...

Comparison of MALDI-TOF-MS and RP-HPLC as Rapid Screening Methods for Wheat Lines With Altered Gliadin Compositions

open access: yesFrontiers in Plant Science, 2020
The wheat gliadins are a complex group of flour proteins that can trigger celiac disease and serious food allergies. As a result, mutation breeding and biotechnology approaches are being used to develop new wheat lines with reduced immunogenic potential.
