Protein isolation experiment
Webb16 jan. 2024 · Researchers routinely use IP to isolate proteins with low abundance from tissue or cell samples for their detection and identification. Since proteins in IP experiments remain post-translationally modified, IP is a core technique in post-translational modification detection assays. WebbThere is growing concern about the emergence and spread of multidrug-resistant Neisseria gonorrhoeae. To effectively control antibiotic-resistant bacterial pathogens, it is necessary to develop new antimicrobials and to understand the resistance mechanisms to existing antibiotics. In this study, we discovered the unexpected onset of drug resistance in N. …
