DPPH has two major applications, both in laboratory research: one is a monitor of chemical reactions involving radicals, most notably it is a common antioxidant assay, [1] and another is a standard of the position and intensity of electron paramagnetic resonance signals.

For each LAMP assay, primers must be specifically designed to be compatible with the target DNA. This can be difficult which discourages researchers from using the LAMP method in their work. [ 1 ] There is however, a free software called Primer Explorer, developed by Fujitsu in Japan, which can aid in the selection of these primers.
Antibody testing has become widely available. It can be done for individual viruses (e.g. using an ELISA assay) but automated panels that can screen for many viruses at once are becoming increasingly common. [citation needed]
Most commonly, antioxidant capacity is measured using the ABTS Decolorization Assay. Other antioxidant capacity assays which use Trolox as a standard include the diphenylpicrylhydrazyl ( DPPH ), oxygen radical absorbance capacity ( ORAC ) and ferric reducing ability of plasma ( FRAP ) assays.

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.
COVID-19 Antigen Rapid Test Kit; the timer is provided by the user. Mucus from nose or throat in a test liquid is placed onto a COVID-19 rapid antigen diagnostic test device. COVID-19 rapid testing in Rwanda. An antigen is the part of a pathogen that elicits an immune response. Antigen tests look for antigen proteins from the viral surface.
