| Popis: | A restriction site-free cloning method has been developed for inserting a PCR product into a vector flexibly and precisely at any desired location with high efficiency. The method uses a pair of DNA integration primers with two portions. The 3′ portion isolates the inserts by PCR, and the 5′ portion integrates the PCR products into the homologous region of the vector. For mutagenesis, a third portion of mutation-generating sequences can be placed in between the 3′ and 5′ portions. This method has been used to clone the E. coli gene that codes for peptidyl-tRNA hydrolase, expressing it as a native protein and as a glutathione S-transferase fusion protein. It was also applied to convert a construct of the E. coli fatty acid biosynthesis protein with an N-terminal hexa-histidine tag into a construct with a C-terminal hexa-histidine tag. |
