Product Specific Information
This 22F6 monoclonal antibody reacts with human, mouse, and canine Helios.
Helios is a zinc-finger transcription factor similar to Ikaros, expressed in hematopoietic stem cells and regulatory T cells, but not in mature B cells, dendritic cells, or myeloid cells.
It can form homodimers or heterodimers with other Ikaros family members to regulate transcription.
Eight isoforms exist, some with dominant-negative functions, upregulated in lymphoid malignancies such as T-acute lymphoblastic leukemia.
22F6 has been reported to cross-react with rat Helios.
Applications Reported: Intracellular staining and flow cytometric analysis.
Applications Tested: Pre-titrated and tested for intracellular staining of mouse lymph node cells using Foxp3/Transcription Factor Buffer Set (Product # 00-5523-00).
Refer to BestProtocols® – Protocol B: One-step protocol for intracellular (nuclear) proteins.
- Recommended use: 5 µL (0.0075 µg) per test
- Test volume: 100 µL
- Cell number: 10⁵–10⁸ cells/test (empirical determination)
- Excitation: 633–647 nm; Emission: 660 nm; Laser: Red
- Filtration: 0.2 µm post-manufacturing filtered
Target Information
Helios belongs to the Ikaros family of zinc-finger proteins (Ikaros, Aiolos, Helios).
These transcription factors regulate lymphocyte development and form homo-/heterodimers to function in early hematopoietic development.
Multiple transcript variants exist, though biological validity of some remains undetermined.
For Research Use Only. Not for use in diagnostic procedures or resale without authorization.
