Microbiology
gene gun
Biology; Microbiology
A device that uses high-pressure gas or another propellant to shoot a spray of DNA-coated microprojectiles into cells and transform them. Sometimes it is called a biolistic device.
acquired enamel pellicle
Biology; Microbiology
A membranous layer on the tooth enamel surface formed by selectively adsorbing glycoproteins (mucins) from saliva. This pellicle confers a net negative charge to the tooth surface.
spread plate
Biology; Microbiology
A petri dish of solid culture medium with isolated microbial colonies growing on its surface, which has been prepared by spreading a dilute microbial suspension evenly over the agar surface.
peplomer
Biology; Microbiology
A protein or protein complex that extends from the virus envelope and often is important in virion attachment to the host cell surface.
spike
Biology; Microbiology
A protein or protein complex that extends from the virus envelope and often is important in virion attachment to the host cell surface.
dipicolinic acid
Biology; Microbiology
A substance present at high concentrations in the bacterial endospore. It is thought to contribute to the endospore's heat resistance.
toxin neutralization
Biology; Microbiology
The inactivation of toxins by specific antibodies, called antitoxins, that react with them.
