Anti-Ki67 Antikörper (A104333)

Immunofluorescent analysis of HeLa cells stained with Anti-Ki67 Antibody (1:5,000 | red), and Anti-Fibrillarin Antibody (1:2,000 | green). The blue is DAPI staining of nuclear DNA. The Ki67 protein accumulates in and around the nucleoli of interphase cells such as those on the right, and the nucleoli are revealed by the Anti-Fibrillarin Antibody. In contrast, cells in the quiescent G0 state such as those on the left are Ki67 negative but fibrillarin positive.

Western blot analysis of equal amounts of cell lysates using Anti-Ki67 Antibody (1:10,000 | green): [1] protein standard (red), [2] rapidly growing HeLa cell cultures, [3] rapidly growing HEK293 cell cultures. Strong double bands larger than the 250kDa standard correspond to full length 345kDa and 395kDa Ki67 isoforms, while smaller proteolytic fragments of these isoforms are also invariably detected on the blot.
