摘要: Abstract A DNA fragment has been constructed that contains many unique cloning sites not present m currently used Escherichia coli plasmid vehicles. Insertion of this into a modified version pBR322 results in an Amp R Tet vector (pJRD158) 3903 bp containing 28 sites, four “almost unique” and eight unassigned 6-bp palindromes. The the additional advantages very high copy number altered incompatibility. latter permits it to be stably maintained same host as pBR322.
