Hello,
does anyone have a personal suggestion regarding Antibodies for Estrogen Receptor alpha and beta ? There are so many out there and usually I go for Cell Signalling, but the references do not really show nice pictures.
I also found a publication , where the Triple negative Breast Cancer cell line MA-MB-231 actually is positive for the ER alpha , a collegue of mine observed the same with an Ab from DAKO doing Western Blot. But my real time PCR was negative, did anybody by chance have similar results/experience with not cell lines that are NOT considered hormone responsive? I thought, maybe the protein is there, but mRNA Levels are not detectable as maybe expressed at a super low level?
Thanks for any kind of help/suggestion.
