Tam (T9262) was obtained from Sigma-Aldrich (St. Louis, MO, USA). Gem was obtained from Sagent Pharmaceuticals (Schaumburg, IL, USA). Antibodies used for western blot analysis were purchased from the following manufacturers: poly(ADP-ribose) polymerase (PARP) (sc-7150) and caspase-3 (sc7148) (Santa Cruz Biotechnology, Inc., Dallas, TX, USA); ERα (2512) and p70 S6 kinase (p70S6k, 2708) (Cell Signaling Technology, Beverly, MA, USA); ERβ (ab3576; Abcam, Cambridge, MA, USA); and β-actin (A3853; Sigma-Aldrich). For the in vitro studies, Tam and Gem were reconstituted just before use in methanol and sterile water, respectively, creating stock solutions that were then diluted in medium to obtain the final concentrations indicated in the figures.

The detailed steps for conducting immunohistochemistry was described previously [11 (link)]. CENPF (ab5) and ERβ (ab3576) were purchased from Abcam. ERβ1 (MCA1974ST), ERβ2 (MCA2279GT) and ERβ5 (MCA4676T) were purchased from AbDSerotec. The specificity of the above antibodies was confirmed by numerous laboratories including ours [11 (link), 28 (link)]. Immunohistochemical method to analyze the optical density was calculated by Image-Pro Plus software.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
