FISH can be incorporated into Lab-on-a-chip microfluidic device. This technology is still in a developmental stage but, like other lab on a chip methods, it may lead to more portable diagnostic techniques. [28] [29] General process of fluorescent in situ hybridization (FISH) used for bacterial pathogen identification.
CISH is similar to FISH in that they are both in situ hybridization techniques used to detect the presence or absence of specific regions of DNA. [1] However, CISH is much more practical in diagnostic laboratories because it uses bright-field microscopes rather than the more expensive and complicated fluorescence microscopes used in FISH.
Microtox is an in vitro testing system which uses bioluminescent bacteria (Allivibrio fischeri, formerly known as Vibrio fischeri) to detect toxic substances in different substrates such as water, air, soils and sediments. [1] Allivibrio fischeri are non-pathogenic, marine, bacteria that luminesce as a natural part of their metabolism. [2]
To detect hybridization of the probe to its target sequence, the probe is tagged (or "labeled") with a molecular marker of either radioactive or (more recently) fluorescent molecules. Commonly used markers are 32 P (a radioactive isotope of phosphorus incorporated into the phosphodiester bond in the probe DNA), digoxigenin , a non-radioactive ...
Testing to identify the species of fish sold in commerce in the US does not appear to be mandatory under US law, but rather facilitates compliance with the law by ensuring the proper species are being sold through a company's supply chain. For these reasons, some companies have decided to implement voluntary testing programs.
Robert Kapas was sitting in a local mall in Atlanta wearing his homemade fish hat, when a man named Leo stopped to ask about it. After hearing the story behind the hat, Leo asked Kapas if he could ...
Before 1989, the only time the NFL played on Christmas was a pair of playoff games in 1971. The NFL adjusted its schedule when Christmas fell on a Sunday to avoid holding games on that day.
Jennaleah “Jenna” Hin, 17, of Henderson, Nevada, was reported missing since Dec. 30 after she reportedly left home following a family dispute
