{"product_id":"biolegend-137241","title":"Biolegend, 137241, Alexa Fluor® 700 anti-mouse\/human Helios Antibody, 25tests","description":"\u003cp\u003eHelios 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.\u003cbr\u003e\n25tests\u003cbr\u003e\nVerified Reactivity: Mouse, Human\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Armenian Hamster\u003cbr\u003e\nImmunogen: Helios peptide (aa 51-107)\u003cbr\u003e\nFormulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and BSA (origin USA)\u003cbr\u003e\nPreparation: The antibody was purified by affinity chromatography and conjugated with Alexa Fluor® 700 under optimal conditions.\u003cbr\u003e\nConcentration: Lot-specific (to obtain lot-specific concentration and expiration, please enter the lot number in our Certificate of Analysis online tool.)\u003cbr\u003e\nStorage \u0026amp; Handling: The antibody solution should be stored undiluted between 2°C and 8°C, and protected from prolonged exposure to light.

For flow cytometric staining, the suggested use of this reagent is 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application. * Alexa Fluor® 700 has a maximum emission of 719 nm when it is excited at 633 nm \/ 635 nm. Prior to using Alexa Fluor® 700 conjugate for flow cytometric analysis, please verify your flow cytometer's capability of exciting and detecting the fluorochrome.
