Cells were harvested and lysed with cell lysis buffer (Cell Signaling Technology, 9803) containing protease inhibitor (Roche, 05892791001) and 1 mM PMSF (MP Biomedicals, ICN19538105). Sample preparation follows NuPAGE Novex protocol. 10% Bis-Tris Gel (Novex, NP0301BOX) was used and transferred to Nitrocellulose Pre-Cut Blotting Membranes (Novex, LC2001). Blocking was performed with 5% milk in Tris-based saline with 0.1% Tween 20 (TBST) for 30 min at RT. After blocking, primary antibodies were diluted in blocking solution and incubated overnight at 4°C. The following antibodies were used with noted dilution ratios: goat anti-FOXA2 (R&D, AF2400, 1:1000), rabbit anti-FOXA2 (Cell Signaling Technology, 3143S, 1:1000), rabbit anti-FOXA1 (Cell Signaling Technology, 58613S, 1:1000), mouse anti-ACTB (Cell Signaling Technology, 3700S, 1:10,000). After washing with TBST, HRP conjugated secondary antibodies in blocking solution were incubated at RT for 1 hour and the gel was visualized using ECL western blotting detection reagent (Amersham, RPN2236). Antibodies for this study are summarized in Table S8.

Cells were fixed by 4% paraformaldehyde (PFA) for 30 min at 4°C, pre-incubated with 5% donkey serum in PBS with 0.1% Triton X-100 (PBST) for 1 hr, incubated with primary antibodies goat anti-FOXA2 (1:1000, R&D Systems), rabbit anti-LMX1 (1:2000, Millipore), mouse anti-Nurr1 (1:1000, Perseus Proteomics), or rabbit anti-TH (1:1000, Millipore) at 4°C overnight, followed by Alexa488, Alexa555 or Alexa647-conjugated secondary antibodies (Invitrogen) for 1 hr and then 4’,6-diamidino-2-phenylindole (DAPI) for 15 min. Images were visualized in a Zeiss LSM 980 Airyscan microscope (Figure S6L).

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.
