Anti h3k4me3

Total proteins were extracted from NRVM cells. NRVM cells lysed in Radio Immunoprecipitation Assay (RIPA) lysis buffers (Beyotime, Nanjing, China). Cell lysates were centrifuged at 12,000 × g for 15 min. The proteins concentration was detected by the BCA method, and equal quantities of protein extracts were loaded on a sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), then transferred onto polyvinylidene fluoride (PVDF) membranes (Millipore Corp., Bedford, MA, U.S.A.). The membranes were blocked with 5% (w/v) non-fat milk for 1 h at room temperature, the membranes were incubated with specific primary antibodies overnight at 4°C. After washing 3 times with TBST, the membranes were incubated with the HRP-linked secondary antibody at room temperature for 1 h, and then washed 3 times with TBST again. Finally, the protein bands on the membranes were detected by chemiluminescent reagents (Beyotime, Nanjing, China). Chemiluminescence signals were quantified using an ECL imager, and analyzed using Quantity One software (Bio-Rad, Hercules, CA, USA). The specific primary antibodies were: anti-GAPDH (Proteintech), anti-Histone3 (Proteintech), anti-H3K4me3 (CST), anti-H3K9me3 (CST), anti-H3K27me3 (CST), anti-H3K36me3 (CST), anti-Flag (Sigma), and anti-Puromycin (Santa Cruz).
