An improved mammalian two-hybrid system designed for interaction trap screening is described in this paper. CV-1/EBNA-1 monkey kidney epithelial cells expressing Epstein-Barr virus nuclear antigen 1 (EBNA-1) were stably transfected with a reporter plasmid for GAL4-dependent expression of the green fluorescent protein (GFP). A resulting clone, GB133, expressed GFP strongly when transfected trans...

We propose a screening method for compounds affecting growth and germination in Candida albicans using a real-time PCR thermocycler to quantify green fluorescent protein (GFP) fluorescence. Using P(ACT1)-GFP and P(HWP1)-GFP reporter strains, the effects of a wide range of compounds on growth and hyphal formation were quantitatively assessed within 3 h after inoculation.

Superpositively charged mutants of green fluorescent protein (GFP) demonstrated a dramatically improved chemical exchange saturation transfer (CEST) MRI contrast compared to their wild type counterparts. The mutants +36 GFP and +48 GFP were successfully expressed in mammalian cells and retained part of their fluorescence, making them a new potential bimodal reporter gene.

The firefly luciferase (Luc) protein and the jellyfish green fluorescent protein (GFP) are two commonly used molecular reporters that can be detected noninvasively in living cells. The properties that make GFP or Luc useful for a particular experimental application are quite distinct. A recombinant protein with both fluorescent and bioluminescent characteristics might take advantage of the stre...

Discovery of Green Fluorescent Protein (GFP) constituted an important improvement for living cell studies on submicron resolution allowing in vivo fluorescence labeling. We studied the photo-physical properties of single GFP molecules incorporated in a charged polyelectrolyte environment by means of single molecule spectroscopy. The fluorescence characteristics change dramatically in terms of p...

Objective: Myh11 encodes a myosin heavy chain protein that is specifically expressed in smooth muscle cells (SMCs) and important for maintaining vascular wall stability. The goal of this study to generate dual reporter mouse line definitive visualization MYH11 + SMCs vivo. Approach Results: We generated knock-in model by inserting LoxP-nlacZ-4XpolyA-LoxP-H2B-GFP-polyA-FRT-Neo-FRT cassette into ...

Transgenic Leishmania infantum promastigotes, which constitutively express green fluorescent protein (GFP) in their cytoplasm, were used to monitor the effects of antileishmanial compounds in real time. The GFP-based assay provided a reliable measure of drug-induced inhibitory effects on protein expression, resulting in a dynamic picture of the responses of leishmanial promastigotes to the comp...

Green fluorescent protein (GFP) is a protein that emits green fluorescence when exposed to a radiation of ultraviolet wavelength range, even without the addition of substrate and cofactor. Because of such characteristics, the usage of GFP is widespread in both in vivo and in vitro applications. In addition, recent advances in biotechnology have enabled GFP to be expressed in various hosts, incl...

The advent of fluorescent proteins (FPs) has redefined the use of fluorescence microscopy in every biological discipline. Green fluorescent protein (GFP) and its variants are commonly used in celluar imaging studies. Recently, a novel fluorescent protein, named vivid Verde Fluorescent Protein (VFP), was isolated from Cyphastrea microphthalma, a scleractinian coral found in the warmer waters of ...
