Fig. 3. CENP-C recognizes DNA within the alpha-satellite arrays. Immunoprecipitated
DNA samples were digested with EcoRI either before (lanes marked with
an asterisk) or after the reversal of crosslinking. Alpha-satellite DNA was
detected as previously described. For the immunoprecipitation with anti-CENP-C
antibodies, two exposure times of the filter are presented: 16 hours and 48
hours. The alpha-satellite immunoprecipitated with anti-CENP-C and anti-CENP-B
antibodies show a very similar band profile when digested with EcoRI either
before or after the reversal of crosslinking.
