Inununoassays based on chemilunlinescent acridinium salts are highlysensitive, robust, and simple (1) but have not been demonstrated in a microplate format because of the lack of suitable luminometers with “on-board” reagent injection systems necessary for quantifying rapidchemiluminescent reactions. We report our initial studies on a two-site immunochemiluminometric assay (IcMA) for thyrotropi...

Abstract The very forward region is one of the most challenging regions to instrument at a future e + − collider. At CEPC, machine-detector interface includes, among others, calorimeter dedicated for precision measurement integrated luminosity per mill level or better. Here we review feasibility such precision, from point view systematic effects arising luminometer mechanical and positioning, b...

The aim of the study was to evaluate the usefulness of bioluminescence in the determination of cleanliness of steel surfaces characterised by different roughness (0.6 and 0.8 μm). The applicability of the method was assessed based on correlations between the number of relative light units (RLU) measured with a luminometer and microbial counts determined by the conventional microbiological metho...

Enzymatic and nonenzymatic chemiluminescence immunoassay methods are widely used as an analytical tool in various bio-molecular detection applications. Here, we demonstrate the synthesis and 1 H NMR analysis of peroxyoxamide reagents and its application for characterization of covalently linked texas red dye with goat anti-mouse IgG antibody and generic goat IgG antibody on mesoporous silica-pa...

This paper describes the development of a platform where a silicon photo-multiplier (SiPM) sensor co-rotates with a “Lab-on-a-Disc” (LoaD). This platform includes a modular data-logger and, to avoid the need for electrical slip rings, it is wirelessly powered. This system is optimized for the detection of chemiluminescence. It is characterized on-disc using dilutions of HRP tagged antibodies an...

The gene that codes for human growth hormone (hGH) is used as a reporter gene to assess changes an effector may have on gene expression of a specific DNA sequence (6). hGH is secreted into the medium of transfected cells following the addition of an appropriate effector; measurement of hGH levels allows for quantification of the degree of activation (or suppression) of gene expression relative ...

The paper describes an integrated luminometer able to perform fluorescence (FL), room temperature phosphorescence (RTP) and chemiluminescence (CL) measurements on seawater samples. The technical details of the instrumentation are presented together with flow injection (FI) manifolds for the determination of cadmium and zinc (by FL), lead (RTP) and cobalt (CL). The analytical figures of merit ar...

There are two methods of measuring the glow a liquid under conditions gas-discharge imaging. This is investigation brightness GD-grams - digital image streamers created these conditions, and direct measurement using luminometer, which carried out during formation streamer gas discharge. In first case, analyzed computer graphics certain software. second, results analyzed. We have example water v...
