Immobilized monolithic enzymatic reactors and its application on analysis of In‐Vitro Fertilization media samples

14-Jun-2017 | Wei‐Qiang Chen, Philipp Obermayr, Urh Černigoj, Jana Vidič, Tanja Panić‐Janković, Goran Mitulović, ELECTROPHORESIS, 2017

Classical proteomics approaches involve enzymatic hydrolysis of proteins (either separated by polyacrylamide gels or in solution) followed by peptide identification using LC‐MS/MS analysis. This method requires normally more than sixteen hours to complete. In the case of clinical analysis, it is ...

A review of blood sample handling and pre‐processing for metabolomics studies

19-May-2017 | Vinicius Veri Hernandes, Coral Barbas, Danuta Dudzik, ELECTROPHORESIS, 2017

Metabolomics has been found to be applicable to a wide range of clinical studies, bringing a new era for improving clinical diagnostics, early disease detection, therapy prediction and treatment efficiency monitoring. A major challenge in metabolomics, particularly untargeted studies, is the ...

Gelified Biofluids for High-Resolution Magic Angle Spinning 1H NMR Analysis: The Case of Urine

05-Jan-2017 | Panteleimon G. Takis; Leonardo Tenori; Enrico Ravera; Claudio Luchinat, Analytical Chemistry, 2017

In this letter, we propose an alternative, effective protocol for metabolomic characterization of biofluids based on their gelification and subsequent application of high-resolution magic angle spinning (HRMAS) 1H nuclear magnetic resonance (NMR). The sample handling is very rapid and ...

Comparative palette characterization of oil‐on‐canvas paintings of two well‐known 19th‐century Colombian artists by confocal Raman spectroscopy

14-Nov-2016 | Diego Badillo‐Sanchez, Wolfram Baumann, Journal of Raman Spectroscopy, 2016

Confocal micro‐Raman spectroscopy has been used for the first time in Colombia to obtain the color palette of two Colombian artists from the 19th century: Jose Maria Espinosa and Epifanio Garay. A new technique to handle and store micro‐samples from oil‐on‐canvas paintings is shown, as well as a ...

The effect of lipid extraction on carbon and nitrogen stable isotope ratios in oyster tissues: Implications for glycogen‐rich species

06-Oct-2016 | H.K. Patterson, R.H. Carmichael, Rapid Communications in Mass Spectrometry, 2016

Abstract Rationale Extraction of lipids from tissues prior to carbon stable isotope analysis (SIA) has become a common practice, despite a lack of species‐specific data to indicate when lipid extraction is needed. Marine invertebrates, including bivalves, are known to store carbon as ...
