A schematic representation of the pBR322 plasmid, one of the first plasmids to be used widely as a cloning vector. Shown on the plasmid diagram are the genes encoded (amp and tet for ampicillin and tetracycline resistance respectively), its origin of replication (ori), and various restriction sites (indicated in blue).
Molecular biology tools. Vector Database—A curated list of over 4,000 vector backbones, including relevant cloning information and bacterial growth conditions.. Sequence Analyzer—An Addgene software tool for creating plasmid maps from sequences with annotated features and restriction sites.
The cloning vector may be DNA taken from a virus, the cell of a higher organism, or it may be the plasmid of a bacterium. The vector contains features that allow for the convenient insertion of a DNA fragment into the vector or its removal from the vector, for example through the presence of restriction sites.
Molecular cloning takes advantage of the fact that the chemical structure of DNA is fundamentally the same in all living organisms. Therefore, if any segment of DNA from any organism is inserted into a DNA segment containing the molecular sequences required for DNA replication, and the resulting recombinant DNA is introduced into the organism from which the replication sequences were obtained ...
Vector map of pUC19. pUC19 is one of a series of plasmid cloning vectors designed by Joachim Messing and co-workers. [1] The designation "pUC" is derived from the classical "p" prefix (denoting "plasmid") and the abbreviation for the University of California, where early work on the plasmid series had been conducted. [2]
The pBR322 plasmid is one of the first plasmids widely used as a cloning vector. Plasmids with specially-constructed features are commonly used in laboratory for cloning purposes . These plasmid are generally non-conjugative but may have many more features, notably a " multiple cloning site " where multiple restriction enzyme cleavage sites ...
A schematic representation of the pBR322 vector with restriction sites indicated in blue. pBR322 is a plasmid and was one of the first widely used E. coli cloning vectors . Created in 1977 in the laboratory of Herbert Boyer at the University of California, San Francisco , it was named after Francisco Bolivar Zapata , the postdoctoral researcher ...
After ligation, transform the vector into bacteria and verify the insert by sequencing. This method can also be used to add new restriction sites to a multiple cloning site. A diagram showing the process of inserting a multiple cloning site into a plasmid vector
