Ames test procedure. The Ames test is a widely employed method that uses bacteria to test whether a given chemical can cause mutations in the DNA of the test organism. More formally, it is a biological assay to assess the mutagenic potential of chemical compounds. [1]
Biology portal; To get a detailed description of the various methods see protein methods and nucleic acid methods. Besides the aforementioned groups of techniques, biotechnology also includes plant tissue culture methods, animal cell culture methods, and microbial fermentation methods.
A separate award for graduate students in biological control was established in 1966. [16] The Harry S. Smith scholarship fund was established for students studying biological control, started with a $15,000 bequest from Smith for that purpose. [17] The archives of Smith's papers are now stored with the Entomology Department of UCR. [18]

The first use of a bioassay dates back to the late 19th century, when the foundation of bioassays was laid down by German physician Paul Ehrlich. [7] He introduced the concept of standardization by the reactions of living matter. [7] [6] His bioassay on diphtheria antitoxin was the first bioassay to receive recognition. [8]
One of the oldest methods is called the multiple tube method. [3] In this method a measured sub-sample (perhaps 10 ml) is diluted with 100 ml of sterile growth medium and an aliquot of 10 ml is then decanted into each of ten tubes. The remaining 10 ml is then diluted again and the process repeated.
Bioinformatics – developing of methods or software tools for storing, retrieving, organizing and analyzing biological data to generate useful biological knowledge [9] Biophysics – study of biological processes by applying the theories and methods that have been traditionally used in the physical sciences [10]
