Protocol for assessing translational regulation in mammalian cell lines by OP-Puro labeling
Summary: Translational regulation is a fundamental step in gene expression with critical roles in biological processes within a cell. Here, we describe a protocol to assess translation activity in mammalian cells by incorporation of O-propargyl-puromycin (OP-Puro). OP-Puro is a puromycin analog that...

| Summary: | Summary: Translational regulation is a fundamental step in gene expression with critical roles in biological processes within a cell. Here, we describe a protocol to assess translation activity in mammalian cells by incorporation of O-propargyl-puromycin (OP-Puro). OP-Puro is a puromycin analog that is incorporated into newly synthesized proteins and is detected by click chemistry reaction. We use OP-Puro labeling to assess translation activity between different cell types or cells under different growth conditions by confocal microscopy and flow cytometry.For complete details on the use and execution of this protocol, please refer to Hsu et al. (2021) and Hsu et al. (2022). : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics. |
