Our Abpromise guarantee covers the use of ab62528 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1.25 µg/ml. Detects a band of approximately 105 kDa (predicted molecular weight: 114 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

Titre using peptide based assay: 1/312500.

IHC-P Use a concentration of 4 - 8 µg/ml.


  • Function
    E3 ubiquitin-protein ligase that mediates monoubiquitination of 'Lys-120' of histone H2B (H2BK120ub1). H2BK120ub1 gives a specific tag for epigenetic transcriptional activation and is also prerequisite for histone H3 'Lys-4' and 'Lys-79' methylation (H3K4me and H3K79me, respectively). Forms a ubiquitin ligase complex in cooperation with the E2 enzyme UBE2E1/UBCH6. It thereby plays a central role in histone code and gene regulation. Required for transcriptional activation of Hox genes.
  • Tissue specificity
    Ubiquitously expressed. Expressed at higher level in testis, heart and pancreas, while it is only weakly expressed in lung, skeletal muscle and small intestine.
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Belongs to the BRE1 family.
    Contains 1 RING-type zinc finger.
