Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 64 kDa).


  • Function

    DNA-binding protein that binds to the 5'GGGAATRCC-3' Ikaros-binding sequence. Transcriptional repressor. Interacts with SPI1 and MITF to repress transcription of the CTSK and ACP5 promoters via recruitment of corepressors SIN3A and CTBP2. May be involved in the development of central and peripheral nervous systems.
  • Tissue specificity

    Highly expressed in skeletal muscle, low levels of expression in heart, thymus, kidney, liver, and spleen. Expressed in the hematopoietic cell lines MOLT-4, NALM-6 and K562. Highly expressed in THP-1 and Mo7e-IL3 cell lines, which have characteristics of myeloid and early megakaryocytic cells respectively.
  • Sequence similarities

    Belongs to the Ikaros C2H2-type zinc-finger protein family.
    Contains 6 C2H2-type zinc fingers.
  • Domain

    The N-terminal zinc fingers are involved in sequence-specific DNA binding and heterotypic associations with other family members.
    C-terminal zinc fingers mediate homodimerization.

    Performed under reducing conditions.

    Predicted band size: 64 kDa
    Observed band size: 70 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 200 kDa (possible non-specific binding), 42 kDa (possible non-specific binding)

    Exposure time: 16 minutes

    Please note that Mouse Liver tissue lysate in lane 3 represents a negative control for IKZF4.

    This blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab155754 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406
