摘要

This protocol provides comprehensive guidance for researchers, including those with limited electron microscopy (EM) experience, on the effective use of genetically encoded, multichannel EMcapsulin reporters in both fluorescence microscopy and EM workflows. EMcapsulins are a set of modular gene reporters that manifest as distinct shapes in EM when expressed in cell culture or model organisms. This protocol encompasses detailed instructions for labeling cells or proteins of interest with fluorescent EMcapsulins, along with biochemical quality control measures. Researchers may also adapt the protocol to develop custom EMcapsulin constructs tailored to their specific experimental requirements.
