Fluorescent proteins for quantitative microscopy: important properties and practical evaluation.

Transient expression of green fluorescent protein in radish (Raphanus sativus) using a turnip mosaic virus based vector

It is possible to use transgenic plants, as bioreactors, for the production of recombinant inexpensive chemicals and drug components. Transient gene expression is an appropriate alternative to stable transformation because it allows an inexpensive and rapid method for expression of recombinant proteins in plant tissues. In recent years, plant viral vectors have been increasingly developed as su...

Evaluation of Relationship between Minimal Residual Disease (MRD) and Relapse in Childhood Acute Lymphoblastic Leukemia (ALL) Using Quantitative Fluorescent PCR

Quantitative lifetime unmixing of multiexponentially decaying fluorophores using single-frequency fluorescence lifetime imaging microscopy.

Fluorescence lifetime imaging microscopy (FLIM) is a quantitative microscopy technique for imaging nanosecond decay times of fluorophores. In the case of frequency-domain FLIM, several methods have been described to resolve the relative abundance of two fluorescent species with different fluorescence decay times. Thus far, single-frequency FLIM methods generally have been limited to quantifying...

A Model to Study the Phenotypic Changes of Insect Cell Transfection by Copepod Super Green Fluorescent Protein (cop-GFP) in Baculovirus Expression System

Background: Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. Methods: The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...

Physiological formation of fluorescent and conductive protein microfibers in live fibroblasts upon spontaneous uptake of biocompatible fluorophores.

We have recently reported initial results concerning an original approach to introduce additional properties into fibrillar proteins produced by live fibroblasts and extruded into the ECM. The key to such an approach was biocompatible, fluorescent and semiconducting synthetic molecules which penetrated spontaneously the cells and were progressively encompassed via non-bonding interactions durin...
