Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 238 kDa.
IHC-P 1/250 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      May be a structural component of the nucleus.
    • Cellular localization
      Nucleus. Chromosome. Dissociates from condensing chromosomes during early prophase, before the complete disintegration of the nuclear lamina. As mitosis progresses it reassociates with telophase chromosomes very early during nuclear reformation, before substantial accumulation of lamins on chromosomal surfaces is evident.
