FIG. 7.

Sir2p is enriched at telomeric foci upon overexpression of Sir3N. The wild-type haploid strain UCC3107, transformed with plasmids pADH (pAAH5) and pADH-SIR3N, was stained with anti-Sir2p, detected by a DTAF-conjugated secondary antibody (green). The DNA was counterstained with POPO-3 (red).
