Fluorescent protein-based ticker tapes (FPTT) record transcriptional histories of multiple promoters on single cellular fibers. Quantitative readout is available at any time point. Cells become biological archives of their own gene expression biorxiv.org/content/10.1...

Our blue FP Electra2 shows excellent brightness & localization in soil-dwelling amoeba D. discoideum as fusion marker, with performance comparable to the golden standard mTagBFP2, all plasmids for Electra2 are available from WeKwikGene wekwikgene.wllsb.edu.cn/publications...

Temporal domain multiplexing enables multiplexed imaging in a single channel with spectrally similar FPs using per-pixel unmixing based on differences in photobleaching rates. To facilitate this approach, we developed new far-red FPs www.biorxiv.org/content/10.1...

Using mBaoJin derivative, Peng Zou lab engineered highly photostable green eFRET GEVI, named Vega, which exhibits more than 20-fold slower photobleaching than Ace-mNeon2, and allows for long-term voltage imaging in brain slice and in vivo in mice biorxiv.org/content/10.1...

to me it was like "try to do as little as possible for as high as possible impact"
piatkevich.bsky.social
Haha, I remember that Ed said each of these to me many times, as well as "your success depends not on the things you do, but often on things you do not do", now I use them in my group!

Xue Han lab from BU used ElectraOFF to achieve routine cellular-resolution imaging over tens of minutes, occasionally up to eighty minutes, in behaving mice with minimal signal loss across neuron types and brain regions www.biorxiv.org/content/10.1...

Hour-long voltage imaging in behaving mice! Capitalizing on the high photostability and brightness of mBaoJin, we developed eFRET GEVIs, named ElectraOFF, which extends reliable single spike detection at cellular resolution beyond one hour biorxiv.org/content/10.1...

Due to its high chemical stability and brightness, mBaoJin is a perfect FP for Expansion Microscopy. Three-dimensional view of expanded HeLa cell coexpressing H2B-mTurquoise2 and Mito (COX8Ax2)-mBaoJin (www.nature.com/articles/s41...)

Soma-targeting of GECIs significantly improves image segmentation, as can be seen from these examples of single-plane 2-photon imaging for FRCaMPi, jRGECO1a, and their soma-localized variant from L2/3 neurons of primary visual cortex in awake mouse journals.plos.org/plosbiology/...

mScarlet3-H (aka mYongHong) makes a great pair with mBaoJin (nature.com/articles/s41...) for long-term live cell imaging. All plasmids can be requested for free from WeKwikGene wekwikgene.wllsb.edu.cn
