Definitions for "Shuttle vector"
A vector (e.g. a plasmid) constructed in such a way that it can replicate in at least two different host species (e.g. a prokaryote and a eukaryote). A DNA recombined into such a vector can be tested or manipulated in several cell types.
A type of cloning vector that contains sequences enabling it to be propagated and maintained in more than one type of host (e.g. E. coli and mammalian cells).
A DNA plasmid capable of replication in multiple host organisms.
