Rhodamine B - an overview | ScienceDirect Topics Before sample preparation, the respective dye was added to the medium to a final concentration of 1M and incubated for 2h. All following incubations were carried out at room temperature and all incubations longer than 1min were performed on an orbital shaker in the dark to prevent preactivation of the dye. Proteins were tagged Strep and Hisx10 N- and C-terminal, respectively. Schindelin, J. et al. Selection was performed using 100gmL1 hygromycin B (ThermoFisher Scientific) and 15gmL1 blasticidine (ThermoFisher Scientific). 3, 23792385 (2012). Subsequently, the FA was quenched by incubating the coverslip for 5min in 100mM NH4Cl in PBS. For activation experiment images were taken in the Cy5 (500ms, ex: 10%), transmission (100ms) and the GFP channel (100ms, ex: 5%) consecutively every 9s. Activation was performed for 50ms after each acquisition cycle. J. Phys. PA-SiR-Halo, PA-SiR-SNAP and PA-SiR-Actin probes (10M) were directly added to the target protein (20M SNAP-tag, 20M HaloTag or 0.4mgmL1 G-actin), or to a bovine serum albumin (Sigma) solution in PBS. PubMed We found that PA-SiR-Halo showed an excellent signal-to-background ratio after activation under no wash conditions (325, mean95% confidence interval, N=119 cells) and that the fluorescence signal after activation was stable over time. Rhodamine WT is distinct from Rhodamine B, for example, because Rhodamine WT (RWT) is water soluble. Fluorogenic probes for live-cell imaging of the cytoskeleton. B.N., M.K.
