Fluorescence expression by bovine embryos was examined after pronuclear microinjection with an enhanced green fluorescent protein (EGFP) cDNA under control of the chicken beta-actin promoter and cytomegalovirus enhancer, as a first step in evaluating the applicability of EGFP for non-invasive selection of transgenic bovine embryos. After injection, developmental competence of the embryos was re...
Adaptation of the vaccinia virus expression system to HeLa S3 suspension bioreactor culture for the production of recombinant protein was conducted. Evaluation of hollow fiber perfusion of suspension culture demonstrated its potential for increased cell density prior to infection. The hollow fiber was also used for medium manipulations prior to infection. Two process parameters, multiplicity of...
Hypothalamic proopiomelanocortin (POMC) neurons are critical for controlling homeostatic functions in mammals. We used a transgenic mouse model in which the POMC neurons were labeled with enhanced-green fluorescent protein (EGFP) to perform visualized, whole-cell patch recordings from pre-pubertal female hypothalamic slices. The mouse POMC-EGFP neurons expressed the same endogenous conductance ...
Interleukin (IL)-6 is a cytokine produced mainly by microglia and astrocytes and plays a pleiotropic role in the central nervous system. In this study, we cloned rat IL-6 cDNA into an enhanced green fluorescent protein (EGFP) or a red fluorescent protein (DsRed2) vector and rat 78-kDa glucose-regulated protein (GRP78) cDNA into an EGFP vector to construct IL-6-EGFP, IL-6-DsRed2, and GRP78-EGFP ...
Bimolecular fluorescence complementation (BiFC) is widely used to detect protein-protein interactions, because it is technically simple, convenient, and can be adapted for use with conventional fluorescence microscopy. We previously constructed enhanced yellow fluorescent protein (EYFP)-based Gateway cloning technology-compatible vectors. In the current study, we generated new Gateway cloning t...
Non-viral transfection protocols are typically optimized using standard cells and reporter proteins, potentially underestimating cellular or transgene effects. Here such effects were studied for two human (Jurkat, HEK-293) and two rodent (CHO-K1, L929) cell lines and three fluorescent reporter proteins. Expression of the enhanced green fluorescent protein (EGFP) was studied under the control of...
All the mouse embryos above belong to the same litter but half of them have inherited a transgene from their father (the green fluorescent adult mouse on the right) that causes them to glow yellowish green under fluorescent light. In these transgenic mice, the enhanced green fluorescent protein (EGFP) is expressed in all cells except hair and erythrocytes. The fact that there are equal numbers ...
The enhanced green fluorescent protein (EGFP) gene is a modified version of the green fluorescent protein gene of the jellyfish Aequorea victoria with a codon usage that corresponds well to that found in many GC-rich streptomycete genes. Here the use of EGFP as a reporter for the analysis of spatially and temporally regulated gene expression in Streptomyces coelicolor A3(2) is demonstrated. The...
Altering a protein's backbone through amino acid deletion is a common evolutionary mutational mechanism, but is generally ignored during protein engineering primarily because its effect on the folding-structure-function relationship is difficult to predict. Using directed evolution, enhanced green fluorescent protein (EGFP) was observed to tolerate residue deletion across the breadth of the pro...
