Depositor Comments

Contains the safe haven site sequence in the backbone of pBluescript II SK- to enable integration into the C. neoformans genome via homologous recombination, in addition to a linker sequence containing multiple rare-cutting restriction enzyme cut sites to facilitate linearization prior to biolistic transformation. Importantly, as the safe haven and marker fragments were inserted into the pBluescript II SK- backbone in place of the f1 origin of replication, each plasmid still retains the original multicloning site and blue/white screening capabilities. Linearization of the safe haven constructs is made possible by the inclusion of a linker containing cut sites for three rare cutting restriction enzymes—BaeI, AscI and PacI. To use the vectors, the gene of interest is subcloned into the standard pBluescript II SK- multicloning site.
