Line Name DNA Construct
1. CSK/pNZ-DT (+/-) In pNZ-DT, the DNA fragment from a Kpnl site in the 5'-non-coding exon to an Ncol site in the kinase domain was replaced with lacZ and neo(r) genes. Since the translatio....
2. CSK/pNZ-DT (-/-) In pNZ-DT, the DNA fragment from a Kpnl site in the 5'-non-coding exon to an Ncol site in the kinase domain was replaced with lacZ and neo(r) genes. Since the translatio....
3. Src (-/-) A replacement vector, src 22, was made using the Pol2sneobpA cassette. This cassette was chosen because the use of a weaker promoter may reduce the number of G418(r) co....
4. CSK/pCZ-DT (-/-) To introduce mutations into the csk gene by homologous recombination in ES cells, 2 types of targeting vector were constructed. The pCZ-DT vector has lacZ and neo[r] (n....
