Abstract:
The carbamyl phosphate synthetase I (CPS,) cDNA probe labelled with alpha ~(35)S-dATP was obtained by using modified nick translation technigue. The specific radioactivity of the obtained probe reached 0.9-1.5?10~8cpm/ug DNA. This probe could be satisfactorily used in RNA-DNA in situ hybrioization for detecting the gene expression of CPS_1 in liver tissue sections. The advantages of using ~(35)S instead of ~(32)P and ~3H for labelling DNA probe were discussed.
