Differential cleavages of disulfide cross-links of protamines in boar sperm nuclei.
Limiting reduction of boar sperm nuclei revealed that disulfide cross-links of the boar protamines complexed with DNA were classifiable into five groups from the differences in their sensitivity toward the reduction. A feature of cross-linkings in boar sperm chromatin and that of bull is discussed.
