Enhanced Green Fluorescent Protein (EGFP) is the most commonly used live cell reporter despite a number of conflicting reports that it can affect cell physiology. Thus far, the precise mechanism of GFP-associated defects remained unclear. Here we demonstrate that EGFP and EGFP fusion proteins inhibit polyubiquitination, a posttranslational modification that controls a wide variety of cellular p...
Cyanobacterial alkaline phosphatases (APases) play a key role in organophosphate utilization freshwater. Tracking the distribution of APases can provide insights into physiological response phytoplankton to phosphorus nutrition. Extracellular APase PhoX, one three prokaryotic families, is important for utilization. Because existing methods only give information on bulk activity, specific contri...
The chimaeric gene encoding a C-terminally truncated form of the S-layer protein SbpA of Bacillus sphaericus CCM 2177 and the EGFP (enhanced green fluorescent protein) was ligated into plasmid pET28a and cloned and expressed in Escherichia coli. Just 1 h after induction of expression an intense EGFP fluorescence was detected in the cytoplasm of the host cells. Expression at 28 degrees C instead...
Embryonic neuroepithelia and adult subventricular zone (SVZ) stem and progenitor cells express nestin. We characterized a transgenic line that expresses enhanced green fluorescent protein (eGFP) specified to neural tissue by the second intronic enhancer of the nestin promoter that had several novel features. During embryogenesis, the dorsal telencephalon contained many and the ventral telenceph...
The red fluorescent protein mCherry is of considerable interest for fluorescence fluctuation spectroscopy (FFS), because the wide separation in color between mCherry and green fluorescent protein provides excellent conditions for identifying protein interactions inside cells. This two-photon study reveals that mCherry exists in more than a single brightness state. Unbiased analysis of the data ...
The ability to study proteins in live cells using genetically encoded fluorescent proteins (FPs) has revolutionized cell biology (1-3). Researchers have created numerous FP biosensors and optimized FPs for specific organisms and subcellular environments in a rainbow of colors (4,5). However, expressing FPs in oxidizing environments such as the eukaryotic endoplasmic reticulum (ER) or the bacter...
A novel strategy was proposed for Ramos cell detection by combining the expression of enhanced green fluorescent protein (eGFP) with the cell aptamer recognition and the triplex molecular beacons. This system was successfully applied to cancer cell detection with high sensitivity and specificity.
We investigated the feasibility of gene transfer into the mouse central nervous system (CNS) by applying nanosecond pulsed laser-induced stress waves (LISWs). Intraventricular or hippocampal injection of a reporter gene [enhanced green fluorescent protein (EGFP)] followed by application of LISWs showed this method to be efficient in the CNS of newborn and adult mice. Cells expressing EGFP resid...
The combination of fluorescent genetically encoded proteins with mouse engineering provides a fascinating means to study dynamic biological processes in mammals. At present, green fluorescent protein (GFP) mice were mainly developed to study gene expression patterns or cell morphology and migration. Here we used enhanced GFP (EGFP) to achieve functional imaging of a G protein-coupled receptor (...
Selection of cells positive for aldehyde dehydrogenase (ALDH) activity from a green-fluorescent background is difficult with existing reagents. Here we report a red-shifted fluorescent substrate for ALDH, AldeRed 588-A, for labelling viable ALDH(pos) cells. We demonstrate that AldeRed 588-A successfully isolates ALDH(hi) human haematopoietic stem cells from heterogeneous cord blood mononuclear ...
