A novel medium-throughput biological assay system for HTLV-1 infectivity and drug discovery
Objective(s): Here, a reporter cell line containing two reporter vectors were developed, in order to monitor the Human T-Lymphotropic Virus type1(HTLV-1) infectivity and the cell viability simultaneously. Materials and Methods: The reporter cell line was constructed by stably transfected baby hamster's kidney cell line (BHK-21), with the genomes expressing two different reporters in separate pl...
متن کاملExpression and Purification of the luciferase enzyme and in Vivo ATP Assay
Introduction: Gene expression and purification of luciferases from the firefly, Lampyris turkestanicus, and optimization of cellular ATP measurements were performed. Methods: cDNA encoding luciferases from Lampyris turkestanicus was transferred from pQE30 vector into pET28a expression vector and pLtu28 was built. Newly constructed vector was expressed in E. coli XL1 Blue and the recombinant l...

Background: Cultivated mammalian cells, because of their capacity for proper protein folding, assembly and post–translational modification, have become the dominant system for production of recombinant proteins in clinical application. Therefore, the quality and efficacy of protein can be superior when expressed in mammalian cells compared to other hosts such as bacteria. Gene reporte...
متن کاملRelative Quantification of Protein-Protein Interactions Using a Dual Luciferase Reporter Pull-Down Assay System
The identification and quantitative analysis of protein-protein interactions are essential to the functional characterization of proteins in the post-proteomics era. The methods currently available are generally time-consuming, technically complicated, insensitive and/or semi-quantitative. The lack of simple, sensitive approaches to precisely quantify protein-protein interactions still prevents...
متن کاملDual luciferase assay system for rapid assessment of gene expression in Saccharomyces cerevisiae.
A new reporter system has been developed for quantifying gene expression in the yeast Saccharomyces cerevisiae. The system relies on two different reporter genes, Renilla and firefly luciferase, to evaluate regulated gene expression. The gene encoding Renilla luciferase is fused to a constitutive promoter (PGK1 or SPT15) and integrated into the yeast genome at the CAN1 locus as a control for no...
