Scientific Data Images for Human Helios Antibody

Detection of Human Helios antibody by Western Blot.

Detection of Human Helios by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line. Gels were loaded with 30 µg of cytoplasmic (Cyto) and 15 µg of nuclear (Nuc) extracts. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human Helios Monoclonal Antibody (Catalog # MAB73091) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Helios at approximately 60 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Helios antibody in Human Thymus by Immunohistochemistry (IHC-P).

Helios in Human Thymus.

Helios was detected in immersion fixed paraffin-embedded sections of human thymus using Mouse Anti-Human Helios Monoclonal Antibody (Catalog # MAB73091) at 0.5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to nuclei in cells around Hassall's corpuscles.

Background: Helios

Helios, also known as IKZF2, is a 70 kDa DNA-binding transcription regulator in the Ikaros family that contains four N-terminal C2H2-type zinc finger domains (aa 112-219) and two C-terminal zinc finger domains (aa 471-523). Helios is expressed in developing hematopoietic and epithelial tissues and in adult T cells and thymic-derived regulatory T cells (Treg). It forms homodimers and also heterodimers with other Ikaros family proteins Ikaros, Pegasus, Eos, and Aiolos. Alternate splicing of human Helios generates a short isoform that lacks three of the the N-terminal zinc finger domains. This isoform is overexpressed in T cell leukemias where it can still dimerize with Ikaros proteins but functions as a dominant negative regulator. Within aa 1-97, human and mouse Helios share 96% aa sequence identity.
