Flow cytometric analysis of EOMES expression in human peripheral blood lymphocytes. Peripheral blood mononuclear cells were stained intracellularly with BD Horizon™ BV421 Mouse Anti-Human CD8 antibody (Cat. No. 562428/562429) and either Alexa Fluor™ 488 Mouse IgG1, κ Isotype Control (Cat. No. 565572; Left Plot) or Alexa Fluor™ 488 Mouse Anti-EOMES antibody (Cat. No. 567169; Right Plot) at 0.06 µg/test using BD Pharmingen™ Transcription Factor Buffer Set (Cat. No. 562574/562725). The bivariate pseudocolor density plot showing the correlated expression of EOMES (or Ig Isotype control staining) versus CD8 was derived from events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometry and data analysis was performed using a BD LSRFortessa™ Flow Cytometer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.
Flow cytometric analysis of EOMES expression in mouse splenic leucocytes. Spleen cells from C57BL/6 mice were stained intracellularly with Alexa Fluor™ 647 Rat Anti-Mouse CD335 (NKp46) antibody (Cat. No. 560755) and either Alexa Fluor™ 488 Mouse IgG1, κ Isotype Control (Left Plot) or Alexa Fluor™ 488 Mouse Anti-EOMES antibody (Right Plot) at 0.06 µg/test using BD Pharmingen™ Transcription Factor Buffer Set. The bivariate pseudocolor density plot showing the correlated expression of EOMES (or Ig isotype control staining) versus CD355 (NKp46) were derived from events with the forward and side light-scatter characteristics of intact leucocytes. Flow cytometry and data analysis was performed using a BD LSRFortessa™ Flow Cytometer System and FlowJo™ software. Data shown on this Technical Data Sheet are not lot specific.

BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and CompBead to ensure that BD Comp beads are appropriate for your specific cellular application.
商品通知
- Since applications vary, each investigator should titrate the reagent to obtain optimal results.
- 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.
- Alexa Fluor® 488 fluorochrome emission is collected at the same instrument settings as for fluorescein isothiocyanate (FITC).
- For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

The X4-83 monoclonal antibody specifically binds to human and mouse Eomesodermin (EOMES), a transcription factor of the T-box family that is also known as T-box brain 2 (TBR2). The aligned sequences of human and mouse EOMES proteins are 86.7% identical and their DNA binding T-box domains are about 74% identical to those of the human and mouse T-bet transcription factors. The name Eomesodermin comes from the Greek word "eo", meaning dawn, and "mesoderm" because it was first identified to be essential for early stages of mesoderm formation. Later in embryonic development, the EOMES transcription factor is important in the differentiation of neurons. EOMES and T-bet are the only T-box transcription factors that are expressed in the immune system, and some of their functions appear to be redundant. EOMES is expressed in cytotoxic T lymphocytes and NK cells, and at lower levels in T helper lymphocytes. EOMES is one of several transcription factors that control the differentiation and survival of effector and memory CD8-positive T lymphocytes, NK cells, and ILC1.
