Abstract Better diagnostic tools are needed to combat the ongoing COVID-19 pandemic. Here, meet this urgent demand, we report a homogeneous immunoassay detect IgG antibodies against SARS-CoV-2. This serological assay, called SATiN, is based on tri-part Nanoluciferase (tNLuc) approach, in which spike protein of SARS-CoV-2 and G, fused respectively two different tNLuc tags, used as antibody probe...

Methods that use bacterial luciferase for the assay of NADH in the range from 1 pmol to 1 nmol are described. Optimal conditions for the assay of glycolytic intermediates, tricarboxylic acid-cycle intermediates and related amino acids from milligram amounts of tissue are presented. The whole spectrum of these intermediates can be determined on about 10 mg of liver tissue. The methods are simple...

Functional in vitro and in vivo reporter gene assays have recently been developed for the rapid determination of exposure to (xeno)estrogens. The in vitro estrogen receptor (ER)-mediated chemically activated luciferase gene expression (ER-CALUX) assay uses T47D human breast cancer cells stably transfected with an ER-mediated luciferase gene construct. In the in vivo assay, transgenic zebrafish ...

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...

Objective(s):An earlier meta-analysis on gene expression data derived from four microarray, two cDNA library, and one SAGE experiment had identified RGS5 as one of only ten non-housekeeping genes that were reported to be expressed in human trabecular meshwork (TM) cells by all studies. RGS5 encodes regulator of G-protein signaling-5. The TM tissue is the route of aqueous fluid outflow, and is r...

We expressed and purified a recombinant P. pyralis luciferase with N-terminal His-tags. The silanized Ni or Cu-loaded magnetic particles were prepared and used to assemble the His-tagged P. pyralis luciferase. This enzyme immobilized on functionalized magnetic nanoparticles (MNPs) via electrostatic interactions of His-tag with Ni2+/Cu2+ ions on the surface of MNPs using si...
