Cells protein lysates were separated by 10% sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) transferred to 0.22 μm NC membranes (Sigma) and incubated with specific antibodies. Autoradiograms were quantified by densitometry (Quantity One software; Bio-Rad). β-actin antibody was used as control. Anti-EZH2, Anti-SUV39H1, Anti-SPRY4 and Anti-HOXB13 was from Abcam (Hong Kong, China).

ChIP assays were performed according to previously described Protocols [28 (link)]. In brief, ChIP was performed using the EZ-Magna ChIP Chromatin Immunoprecipitation Kit (Millipore). The antibodies were obtained from Abcam: anti-H3K9 (ab8898) and anti-SUV39H1 (Abcam, ab12405). The DNA was detected through RT-qPCR and primers were provided in Additional file 2: Table S2.

ChIP-qPCR for Epigenetic Markers

Check if the same lab product or an alternative is used in the 5 most similar protocols
Chromatin immunoprecipitation was performed as previously described [40 (link)]. Briefly, the cells were incubated with 1% formaldehyde for cross-linking, followed by shearing. The chromatin solution was obtained by centrifugation at 13,000 rpm at 4 °C rpm for 20 min. A small portion (5%) of the chromatin solution was reserved as input DNA, and the remaining solution was incubated with the primary antibodies and protein A agarose/salmon sperm (Millipore, #16-157) overnight at 4 °C. Next, the chromatin fragments were de-crossed from the proteins and eluted to be subjected to qPCR using primers listed in Table 2. Anti-HP1γ (Millipore, 05-690), anti-trimethyl Histone H3 Lys9 (Millipore, 07-442), anti-G9a (Abcam, ab40542), and anti-Suv39h1 (Abcam, ab12405) were used for ChIP.

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.
