Flow cytometric analysis of HeLa cells (blue) and MUG-Chor1 cells (green) using Brachyury (D2Z3J) Rabbit mAb (PE Conjugate) (solid line) compared to concentration-matched Rabbit (DA1E) mAb IgG XP® Isotype Control (PE Conjugate) #5742 (dashed line).
This Cell Signaling Technology antibody is conjugated to phycoerythrin (PE) and tested in-house for direct flow cytometric analysis in human cells. This antibody is expected to exhibit the same species cross-reactivity as the unconjugated Brachyury (D2Z3J) Rabbit mAb #81694.
Supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg/ml BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.
NOTE: Prepare solutions with RODI (reverse osmosis deionized) or equivalent grade water.
NOTE: Immunostaining of surface antigens should be performed on live cells prior to fixation/permeabilization, as per manufacturer’s requirements.

Brachyury (D2Z3J) Rabbit mAb (PE Conjugate) recognizes endogenous levels of total Brachyury protein.
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro256 of human Brachyury protein.
Brachyury protein, encoded by the T gene, is a transcription factor that is vital for the formation of posterior mesoderm and axial development during vertebrate embryogenesis (1). In the mouse, brachyury is necessary for mesodermal morphogenetic cell movements during gastrulation. Brachyury mutant mice die in utero and display deficient mesoderm formation including an abnormal notochord, missing posterior somites, and a reduced allantois (2). Human brachyury is expressed in the notochord, as well as in chordoma tumors that occur along the spine, making it a good marker for notochord and notochord-derived tumors (3,4). A common polymorphism in the human T gene has also been shown to be associated with development of the multifactorial neural tube defect, spina bifida (5,6).
