Addgene facilitates the exchange of genetic material between laboratories by offering plasmids and their associated cloning data to non-profit and academic laboratories around the world. Addgene provides a free online database of plasmid cloning information and references, including lists of commonly used vector backbones, popular lentiviral ...
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 ...
pSC101 is a DNA plasmid that is used as a cloning vector in genetic cloning experiments. pSC101 was the first cloning vector, used in 1973 by Herbert Boyer and Stanley Norman Cohen. Using this plasmid they have demonstrated that a gene from a frog could be transferred into bacterial cells and then expressed by the bacterial cells.
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 ...
P1 vectors also contain a P1 plasmid replicon, which ensures only one copy of the vector is present in a cell. However, there is a second P1 replicon- called the P1 lytic replicon- that is controlled by an inducible promoter. This promoter allows the amplification of more than one copy of the vector per cell prior to DNA extraction. [2] bac vector
The vir helper plasmid contains the vir genes that originated from the Ti plasmid of Agrobacterium. These genes code for a series of proteins that cut the binary vector at the left and right border sequences, and facilitate transfer and integration of T-DNA to the plant's cells and genomes, respectively.
Another vector used in genetic engineering is pUC19, which is similar to pUC18, but its polylinker region is reversed. E.coli is also commonly used as the bacterial host because of the availability, quick growth rate, and versatility. [7] An example of a plasmid cloning vector which modifies the inserted protein is pFUSE-Fc plasmid.
