Ronnie, I don't have any problems with 4-color fluorescence staining using mouse monoclonal Ki67 conjugated with AlexaFluor488 from BD Pharmingen and rabbit monoclonal PHH3 conjugated with AlexaFluor 555 from Cell Signaling (I also added for complete set rabbit monoclonal gammaH2A.X conjugated with AF647 from Cell Signaling and DAPI). All four colors work good. There was no any masking for PHH3. It looks like chromosome staining for Ki67 was a little less crisp than in case when I used combination with antibody against non-phosphorilated H2A.X histone instead of Ki67. So, probably there is a little masking of Ki67 rather than PHH3.

Ki-67 tends to mask most of the PHH3 staining irrespective of which antibody we use first. Individually, both antibodies have clean and crisp localization. I have seen pictures in articles and on-line of results but am far from attaining anything like these. We are using the Refine DAB and AP Red kits from Leica on the Bonds. Ki-67 is from Leica and PHH3 from Cell Marque Any help or suggestions welcome Thanks Ronnie Ronnie Houston, MS HT(ASCP)QIHC Anatomic Pathology Manager ChildLab, a Division of Nationwide Children's Hospital www.childlab.com 700 Children's Drive Columbus, OH 43205 (P) 614-722-5450 (F) 614-722-2899 ronald.hous...@nationwidechildrens.org<mailto:ronald.hous...@nationwidechildrens.org> www.NationwideChildrens.org<http://www.NationwideChildrens.org> "One person with passion is better than forty people merely interested." ~ E.M.
