QA20A52_PURE_Helios_RECOM_Antibody_102621
C57BL/6 mouse splenocytes were surface stained with anti-mouse CD4 APC and then fixed and perm using True-Nuclear™ Transcription Factor Buffer Set. Cells were then intracellularly stained with purified anti-Helios recombinant (clone QA20A52) (left) or rat IgG1, κ isotype control (right) followed by anti-rat IgG1 PE.

Description

Helios is a member of the Ikaros family of zinc finger transcription factors. It contains a C-terminal region composed of 2 zinc-finger domains that mediate dimerization between the family members. Helios was originally cloned from a mouse thymoma line. It is mainly expressed in peripheral T cells and thymocytes. It is found at high levels in a subpopulation of regulatory T cells. Helios plays an important role in T cell development and homeostasis. Overexpression of Helios profoundly alters αβ T cell differentiation and activation. It has been determined that silencing of Helios in B cells is critical for maintaining normal B cell function. Helios is also involved in tumor immunity.
