Isotype
Armenian Hamster IgG
Specificity
The armenian hamster monoclonal antibody 22F6 recognizes Helios, a transcription factor expressed in some hematopoietic stem cells, and at high levels in thymic-derived regulatory T cells.
Application
FC (QC tested)
Application details
Flow cytometry: The reagent is designed for analysis of human blood cells using 10 μl reagent / 100 μl of whole blood or 106 cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.
Immunogen
Peptide coresponding to the amino acids 51-107 of Helios
Other names
ANF1A2, IKZF2
Preparation
The purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. The conjugate is purified by size-exclusion chromatography.
Formulation
Stabilizing phosphate buffered saline (PBS) solution containing 15mM sodium azide
Storage and handling
Store in the dark at 2-8°C. Do not freeze. Avoid prolonged exposure to light. Do not use after expiration date stamped on vial label.
