Anti-H/M Helios PE,22F6
特異性
The armenian hamster monoclonal antibody 22F6 recognizes Helios antigen, a transcription factor expressed in some hematopoietic stem cells, and at high levels in thymic-derived regulatory T cells.
抗原情報
Helios (IKZF2; Ikaros family zinc finger protein 2) is a hematopoietic-specific transcription factor involved in the regulation of lymphocyte development, together with other members of this family, such as Aiolos and Ikaros. Helios forms homo- and heterodimers with these proteins and is thought to function predominantly in early hematopoietic development. Expression of Helios, Aiolos and Ikaros is restricted to cells of the hematopoietic system, whereas other family members, Eos and Pegassus, are more widely expressed. Helios is expressed at early stages of thymocyte development. In mature T cells, Helios has been strongly associated with Treg cells.
利用方法
The reagent is designed for Flow Cytometry analysis of human blood cells. Recommended usage is 10 µl reagent / 100 µl of whole blood or 10^6 cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.
保存方法
Avoid prolonged exposure to light. Store in the dark at 2-8°C. Do not freeze.
安定性情報
Do not use after expiration date stamped on vial label.
