Immunodiffusion is a laboratory technique used to detect and quantify antigens and antibodies by observing their interactions within a gel medium. [1] This technique involves the diffusion of antigens and antibodies through a gel, usually agar, resulting in the formation of a visible precipitate when they interact.
The school's mission is to produce experimental test pilots, flight test engineers, and flight test navigators to lead and conduct test and evaluation of aerospace weapon systems. [1] The school was established on September 9, 1944, as the Flight Test Training Unit at Wright-Patterson Air Force Base (AFB) in Dayton, Ohio. [2]
A gel plate is cut to form a series of holes ("wells") in an agar or agarose gel. A sample extract of interest (for example human cells harvested from tonsil tissue) is placed in one well, sera or purified antibodies are placed in another well and the plate left for 48 hours to develop.

Oakley, known for his work in the Fluorine absorption dating of fossils by fluorine content, [ 1 ] [ 2 ] was instrumental in the exposure [ 3 ] of the Piltdown Man hoax in the 1950s.
The Oakley-class lifeboat refers to two types of self-righting lifeboat operated by the Royal National Lifeboat Institution (RNLI) around the coast of the United Kingdom and Ireland between 1958 and 1993. The 37-foot (11.3 m) Oakley was designed for carriage launching, while the larger 48-foot-6-inch (14.8 m) version was designed for slipway ...
Patients swallow urea labelled with an uncommon isotope, either radioactive carbon-14 (nowadays preferred in many countries) or non-radioactive carbon-13.In the subsequent 10–30 minutes, the detection of isotope-labelled carbon dioxide in exhaled breath indicates that the urea was split; this indicates that urease (the enzyme that H. pylori uses to metabolize urea to produce ammonia) is ...
