Caption
LIN54 Western (Lane 5). Predicted size was 82 kDa. The observed size was 100 kDa, which is the same as an observed band of 100 kDa seen in https://www.abcam.com/lin54-antibody-ab138425.html. Lighter band at 70 kDa could correspond to another isoform that shares the same tagged stop codon. Each nuclear protein isolate (151 mcg - HSF4, 101 mcg - KLF16, 198 mcg - LIN54, 90 mcg - MED1, 180 mcg - MXD1, and 196 mcg - NR0B2) was standardized in a solution containing a volume of 2% Halt Protease and Phosphatase Inhibitor Single-Use Cocktail Mixture (Thermo Fisher Scientific), NuPage Sample Reducing Agent 10X, and NuPage LDS Sample Buffer 4X (Thermo Fisher Scientific). After heating the solution for 15 minutes at 90C followed by cooling on ice, the protein samples were loaded onto a NuPage 4-12% Bis-Tris gel (Thermo Fisher Scientific) and separated using a PowerEase 90W system (Thermo Fisher Scientific) running at 150 V for 1 hour. The protein bands were transferred to a nitrocellulose membrane using the Invitrogen iBlot 2 System (Thermo Fisher Scientific), and blocked overnight at 4C in 5% milk solution with gentle rocking. The membrane was treated with a 1:5000 dilution of monoclonal M2- Peroxidase-conjugated ANTI-FLAG antibody (diluted in 5% BSA solution) (Sigma- Aldrich; cat# A8592) for 1 hour. Following four 5-minute washes with 1X TBST, visualization was attained with the Super Signal West Femto solution kit (Thermo Fisher Scientific) and a MyECL Imager (Thermo Fisher Scientific). The second western blot image depicts negative controls prepared with HepG2 nuclear lysate (Lane 2) and K562 nuclear lysate (Lane 3).
