Application Abreviews Notes
ChIP Use at an assay dependent concentration. PubMed: 19721712
ELISA 1/1000.
IHC-P 1/50 - 1/100.
WB 1/100 - 1/500. Detects a band of approximately 45 kDa (predicted molecular weight: 45 kDa).


  • Function
    Multifunctional transcription factor that exhibits positive and negative control on a large number of cellular and viral genes by binding to sites overlapping the transcription start site. May play an important role in development and differentiation. The function of YY1 as an activator or a repressor is specified by the presence of other proteins. For example it acts as a repressor in absence of adenovirus E1A protein but as an activator in its presence.
  • Sequence similarities
    Belongs to the YY transcription factor family.
    Contains 4 C2H2-type zinc fingers.
  • Cellular localization
    Nucleus matrix. Associated with the nuclear matrix.

Thank you for your enquiry. Unfortunately none of our YY1 antibodies has been tested in ChIP therefore we do not know what suitable genes would be a good positive control. I suggest looking in the literature on this protein and hope this will be able t...
