Colorimetric analysis is a method of determining the concentration of a chemical element or chemical compound in a solution with the aid of a color reagent.It is applicable to both organic compounds and inorganic compounds and may be used with or without an enzymatic stage.
Loop-mediated isothermal amplification (LAMP) primers [1] Loop-mediated isothermal amplification (LAMP) product [1]. In LAMP, the target sequence is amplified at a constant temperature of 60–65 °C (140–149 °F) using either two or three sets of primers and a polymerase like Bst Klenow fragment with high strand displacement activity in addition to a replication activity.
Colorimetric assays use reagents that undergo a measurable color change in the presence of the analyte. They are widely used in biochemistry to test for the presence of enzymes, specific compounds, antibodies, hormones and many more analytes. For example, para-Nitrophenylphosphate is converted into a yellow product by alkaline phosphatase enzyme.
The range of applications for multi-mode plate readers is extremely large. Some of the most common assays are: ELISAs; Protein and cell growth assays; Protein–protein interaction; Reporter assays; Nucleic acid quantitation; Molecular interactions; Enzyme activity; Cell toxicity, proliferation, and viability; ATP quantification; Immunoassays [11]
ATP is quantified by measuring the light produced through its reaction with the naturally occurring firefly enzyme luciferase using a luminometer. The amount of light produced is directly proportional to the amount of ATP present in the sample. ATP tests can be used to: Control biological treatment reactors; Guide biocide dosing programs
The Folin–Ciocâlteu reagent (FCR) or Folin's phenol reagent or Folin–Denis reagent, is a mixture of phosphomolybdate and phosphotungstate used for the colorimetric in vitro assay of phenolic and polyphenolic antioxidants, also called the gallic acid equivalence method (GAE). [1] It is named after Otto Folin, Vintilă Ciocâlteu, and Willey ...
ATP cleavage is tightly linked to substrate translocation, as the energy for the substrate translocation is derived from ATP hydrolysis. ATP hydrolysis yields inorganic phosphate (Pi), which can be measured by a simple colorimetric reaction. The amount of Pi liberated is directly proportional to the activity of the transporter. [1]
