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.

Application

ICFC - Quality tested
Recommended Usage

Each lot of this antibody is quality control tested by intracellular flow cytometry using our True-Nuclear™ Transcription Factor Staining Protocol.
For flow cytometric staining, the suggested use of this reagent is 5 µl per 106 cells in 100 µl volume or 5 µl per 100 µl whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 647 has a maximum emission of 668 nm when it is excited at 633nm / 635nm.
