Preparation And Storage
Product Notices
- This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
- An isotype control should be used at the same concentration as the antibody of interest.
- Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- Pacific Blue™ is a trademark of Molecular Probes, Inc., Eugene, OR.
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

The R32-1149 monoclonal antibody specifically binds to Ikaros, which is encoded by IKZF1 (IKAROS family zinc finger 1). Ikaros is also known as Lymphoid transcription factor LyF-1 (LYF1) and ZNFN1A1 [Zinc finger protein, subfamily 1A, 1 (Ikaros)]. Ikaros belongs to the IKAROS family of zinc-finger transcription factors. This DNA-binding transcription factor forms homodimers and heterodimers with other IKAROS family members. It is involved in the development of lymphoid tissues and remains abundantly expressed in the thymus and by cells within peripheral lymphoid tissues. Ikaros functions in the maturation, differentiation, and homeostasis of various hematopoietic cells including T lymphocytes, B cells, NK cells, and neutrophils. Ikaros regulates the expression of a number of genes including various genes expressed during early stages of B- and T-cell development. Several alternatively-spliced human Ikaros isoforms have been described. Abnormal expression of different Ikaros isoforms has been associated with hematologic malignancies. Flow cytometric analysis of 293F cells transfected with members of the IKAROS family has demonstrated that clone R32-1149 is negative on Helios, Aiolos, and Eos transfectants.
The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.
