Summary: Rapid immunoprecipitation mass spectrometry of endogenous protein (RIME) is a technique to study protein complexes on chromatin. The protocol below describes specific steps for RIME analysis of the male human-derived prostate cancer cell line LNCaP. This approach can also be applied to other prostate cancer cell lines such as 22Rv1, DU145, and PC3. For other cell types, we recommend optimizing the number of cell culture plates to ensure adequate sample for mass spectrometry protein detection.For complete details on the use and execution of this protocol, please refer to Mohammed et al. (2016) and Dufour et al. (2022). : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
