A plasmid that can replicate in one, or at most a few, different bacterial species.
Industry:Biotechnology
A plasmid that confers antibiotic resistance to a bacterium.
Industry:Biotechnology
A plasmid that only replicates along with the main bacterial chromosome and is present as a single copy, or at most several copies, per cell.
Industry:Biotechnology
A plasmid that provides a function or functions to another plasmid in the same cell.
Industry:Biotechnology
A plasmid that replicates independently of the main bacterial chromosome and is present in 10-500 copies per cell.
Industry:Biotechnology
A plasmid vector which contains the two cos (cohesive) ends of phage lambda (1) and one or more selectable markers such as an antibiotic resistance gene. Cosmids exploit certain properties of phage lambda (1) to enable large, 40-50 kb, DNA fragments to be cloned at high efficiency. Cosmids and cosmid recombinants replicate as plasmids.
Industry:Biotechnology
A plastic sheet impregnated with a rare-earth compound, such as calcium tungstate, which absorbs ß radiation and emits light. When placed on one side of a piece of X-ray film with a radioactive sample on the other side, the intensifying screen will capture some of the ß emissions which pass through the film, blackening the X-ray film and so greatly enhancing the sensitivity of the detection. An intensifying screen is used in Southern and northern blotting procedures.
Industry:Biotechnology
A platform fitted with clips for grasping Erlenmeyer flasks, with set or variable speed control. Shaking speed must be adjusted for gentle and even agitation of suspension cultures.
