    Protocol

    Specificity / Sensitivity

    Helios (E4L5U) Rabbit mAb recognizes endogenous levels of total Helios protein. Non-specific non-nuclear staining was observed in some mouse tissues by immunohistochemistry.

    Species Reactivity:

    Human, Mouse

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Bovine

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly73 of human Helios protein.

    Background

    Helios (Ikaros family zinc finger 2, IKZF2) is an Ikaros family transcription factor composed of several zinc fingers that mediate DNA binding and homodimerization or heterodimerization with other Ikaros family proteins (1,2). In the hematopoietic system, Helios expression is restricted to T cells and early hematopoietic progenitors (1,2). In regulatory T cells, expression of Helios contributes to an anergic phenotype by binding to the IL-2 promoter and suppressing IL-2 transcription (3). In addition, alteration of the corresponding Helios gene IKZF2 is one hallmark of low-hypodiploid acute lymphoblastic leukemia (4).
