  • Function
    Polycomb group (PcG) protein. Catalytic subunit of the PRC2/EED-EZH1 complex, which methylates 'Lys-27' of histone H3, leading to transcriptional repression of the affected target gene. Able to mono-, di- and trimethylate 'Lys-27' of histone H3 to form H3K27me1, H3K27me2 and H3K27me3, respectively. Required for embryonic stem cell derivation and self-renewal, suggesting that it is involved in safeguarding embryonic stem cell identity. Compared to EZH1-containing complexes, it is less abundant in embryonic stem cells, has weak methyltransferase activity and plays a less critical role in forming H3K27me3, which is required for embryonic stem cell identity and proper differentiation.
  • Sequence similarities
    Belongs to the histone-lysine methyltransferase family. EZ subfamily.
    Contains 1 SET domain.
  • Cellular localization
    Nucleus. Colocalizes with trimethylated 'Lys-27' of histone H3.

Thank you for sending the image of your blots.

When you use the PVDF membrane, are you pre-wetting it with methanol? Because PVDF is hydrophobic, it may not properly bind the blocking agent without the pre-wetting step. This could potentially...

Thank you for your phone call. As we discussed, it is possible that your 6 x 15 minute washes are washing the blocking agent off your membrane. It may help to reduce the wash time to 3 x 5 min, shorten the primary antibody incubation to 1 hour at RT, a...

Thank you for contacting us. We do not have tests against purified Ezh1 or Ezh2 but a BLAST search of the immunogen sequence returns only Ezh1, so it is expected that the antibody is not capable of detecting Ezh2. I hope this information is helpf...
