Detection of opines by colorimetric assay
Analytical Biochemistry, 1987A colorimetric procedure for confirming the presence of arginine-derived opines (nopaline and octopine) in plant tissue extracts is described. Those materials are widely used as markers of plant cell transformation and tumorigenesis mediated by the tumor-inducing plasmids of Agrobacterium tumefaciens.

Quantitative PCR with colorimetric detection
Research in Immunology, 1996We describe a quantitative polymerase chain reaction (PCR) technique with a colorimetric read-out, which enables quantitation of various sequences on a single microplate within one day. Using the quantitation of human IL10 and beta-actin transcripts, we show that this technique provides better reproducibility, as results are derived from a series of ...

Colorimetric Silver Detection of DNA Microarrays
Analytical Biochemistry, 2001Development of microarrays has revolutionized gene expression analysis and molecular diagnosis through miniaturization and the multiparametric features. Critical factors affecting detection efficiency of targets hybridization on microarray are the design of capture probes, the way they are attached to the support, and the sensitivity of the detection ...

Glyconanoparticles for the Colorimetric Detection of Cholera Toxin
Analytical Chemistry, 2007Cholera continues to represent a major threat to human health, particularly in developing countries. Death can be readily avoided when medical treatment is rapidly administered. In order to provide a means of detecting the bacterially secreted toxin, we have developed a simple, yet rapid, bioassay for the cholera toxin.

Nanozymatic Degradation and Simultaneous Colorimetric Detection of Tetracycline
Food Chemistry, 2022Tetracycline (TC) is a broad-spectrum antibiotic that can enter and accumulate in the human body via the food chain. Even in small concentrations, TC can cause several malignant health effects. We developed a system to simultaneously degrade the presence of TC in food matrices using titanium carbide MXene (FL-Ti3C2Tx).

Labeling and Colorimetric Detection of Nonisotopic Probes
Current Protocols in Molecular Biology, 1992AbstractAlthough a number of different nonisotopic labels have been described in the literature, biotin and digoxigenin are used most frequently and are commercially available. Either label can be easily incorporated into DNA probes and be detected colorimetrically; a number of fluorochromes, as well as alkaline phosphatase and horseradish peroxidase ...

Fluorescent and colorimetric probes for detection of thiols
Chemical Society Reviews, 2010Due to the biological importances of thiols, such as cysteine, homocysteine and glutathione, the development of optical probes for thiols has been an active research area in recent few years. This critical review focuses on the fluorescent or colorimetric sensors for thiols according to their unique mechanisms between sensors and thiols, including ...
