Immunofluorescent detection of protein CoAlation in mammalian cells under oxidative stress.

ABSTRACT: Previously, we reported the generation and characterisation of highly specific anti-CoA monoclonal antibodies capable of recognizing CoA in various immunological assays. Utilizing these antibodies in conjunction with mass spectrometry, we identified a wide array of cellular proteins modified by CoA in bacteria and mammalian cells. Furthermore, our findings demonstrated that such modifications could be induced by oxidative or metabolic stress. This study advances the utility of anti-CoA monoclonal antibodies in analysing protein CoAlation, highlighting their effectiveness in immunofluorescent assay. Our data corroborates a significant increase in cellular protein CoAlation induced by oxidative agents. Additionally, we observed that hydrogen-peroxide induced protein CoAlation is predominantl
