[Formation of DNA-protein links upon interaction between sodium bisulfite and phage DNP].

The conditions for linkage formation in phages Sd and P22 DNP under effects of sodium bisulfite were studied. Th linkage was estimated by the fall in phage infectiosity. After removal of the reagent excess prior to inoculation the modified phage was transferred to various buffers (12 salt systems). The correlation between infectiosity of preparations and changes in their CD spectra in corresponding calt solutions was established.
