Rabbit anti tet1

For Western blot analysis, total proteins were extracted from cell lines (1×10⁶ cells/well) supplemented with protease inhibitors cocktail with protein extraction buffer (Novagen, Madison, WI, USA) with 2 × SDS lysis buffer. Protein concentrations were quantified using the BCA protein assay kit (TIANGEN, Beijing, China). Proteins were separated using 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and then transferred onto a polyvinylidene difluoride (PVDF) membrane. Subsequently, membranes were blocked with 5% non-fat milk powder dry milk in Tris-buffered saline with Tween-20 (TBS-T; 0.1% Tween-20 in TBS) and incubated with primary antibodies including rabbit anti-TET1 (Abcam), anti-Bax (Abcam), anti-Bcl2 (Abcam) and mouse anti-GAPDH (Abcam), respectively each at a dilution of 1:2000 in 5% blocking buffer overnight at 4ºC. Then, the membranes were washed twice with TBS-T, and membranes were incubated with HRP-conjugated secondary antibodies (anti-mouse or anti-rabbit, Invitrogen) for 1 h at room temperature (RT). The target bands were visualized using the Chemiluminescence Kit, and the protein bands were quantified using ECL Super Signal (Pierce, USA).
