Application Abreviews Notes
ELISA 1/10000.
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.
WB 1/500 - 1/1000. Detects a band of approximately 170 kDa (predicted molecular weight: 180 kDa).


  • FunctionComponent of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.
  • Tissue specificityUbiquitously expressed.
  • Sequence similaritiesBelongs to the Mediator complex subunit 1 family.
  • Post-translational
    Phosphorylated by MAPK1 or MAPK3 during G2/M phase which may enhance protein stability and promote entry into the nucleolus. Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localizationNucleus. A subset of the protein may enter the nucleolus subsequent to phosphorylation by MAPK1 or MAPK3.

    Lane 1 : extracts from Jurkat cells, without immunising peptide
    Lane 2 : extracts from Jurkat cells, with immunising peptide

    Predicted band size : 180 kDa
    Observed band size : 170 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 110 kDa. We are unsure as to the identity of these extra bands.
  • Immunohistochemistry analysis of paraffin-embedded human breast carcinoma tissue using 1/50 ab64965, after antigen retrieval by boiling in a pressure cooker for 2-3 min. Polymer system was used for signal enhancing and DAB staining was performed for visualising the signal.
