摘要: ABSTRACT To expand the toolbox of imaging in living cells, we have engineered a new single chain variable fragment (scFv) that binds classic linear HA epitope with high affinity and specificity vivo. The resulting probe, which call frankenbody, is capable lighting up multiple colors HA-tagged nuclear, cytoplasmic, membrane proteins diverse cell types. frankenbody also enables state-of-the-art single-molecule experiments, demonstrate by tracking mRNA translation dynamics U2OS cells neurons. In combination SunTag, track two species simultaneously to comparative studies can now be done genetically encoded tools alone. Finally, use precisely quantify expression tagged developing zebrafish embryos. versatility makes it powerful tool for protein One-sentence summary A encodable intracellular single-chain selectively (YPYDVPDYA) organisms used translation, localization, dynamics.
