Green tea-flavored yōkan, a popular Japanese red bean jelly made from agar A blood agar plate used to culture bacteria and diagnose infection. Agar (/ ˈ eɪ ɡ ɑːr / or / ˈ ɑː ɡ ər /), or agar-agar, is a jelly-like substance consisting of polysaccharides obtained from the cell walls of some species of red algae, primarily from “ogonori” and “tengusa”.
The disk diffusion test (also known as the agar diffusion test, Kirby–Bauer test, disc-diffusion antibiotic susceptibility test, disc-diffusion antibiotic sensitivity test and KB test) is a culture-based microbiology assay used in diagnostic and drug discovery laboratories. In diagnostic labs, the assay is used to determine the susceptibility ...
Microbial cultures are foundational and basic diagnostic methods used as research tools in molecular biology. The term culture can also refer to the microorganisms being grown. Microbial cultures are used to determine the type of organism, its abundance in the sample being tested, or both.
An agarose gel in a tray used for gel electrophoresis. Agarose is a heteropolysaccharide, generally extracted from certain red algae. [1] It is a linear polymer made up of the repeating unit of agarobiose, which is a disaccharide made up of D-galactose and 3,6-anhydro-L-galactopyranose.
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.
An agar plate – an example of a bacterial growth medium*: Specifically, it is a streak plate; the orange lines and dots are formed by bacterial colonies.. A growth medium or culture medium is a solid, liquid, or semi-solid designed to support the growth of a population of microorganisms or cells via the process of cell proliferation [1] or small plants like the moss Physcomitrella patens. [2]
Agarose gel electrophoresis is a method of gel electrophoresis used in biochemistry, molecular biology, genetics, and clinical chemistry to separate a mixed population of macromolecules such as DNA or proteins in a matrix of agarose, one of the two main components of agar.
1.5% agar - this gives the mixture solidity; 0.5% sodium chloride - this gives the mixture proportions similar to those found in the cytoplasm of most organisms; distilled water - water serves as a transport medium for the agar's various substances; pH adjusted to neutral (6.8) at 25 °C (77 °F). Nutrient broth has the same composition, but ...
