Specificity
The immunogen used to raise this antibody has 81% homology with the Mouse Brachyury protein. Some customers have successfully used ab20680 on mouse samples, however we have not been successful detecting Brachyury in this species in our own testing and therefore cannot guarantee mouse reactivity. Please contact Abcam Scientific Support for more information.

Target
-
Function
Involved in the transcriptional regulation of genes required for mesoderm formation and differentiation. Binds to a palindromic site (called T site) and activates gene transcription when bound to such a site. -
Involvement in disease
Genetic variations in T are associated with susceptibility to neural tube defects (NTD) [MIM:182940]. NTD are common congenital malformations. Spina bifida, which results from malformations in the caudal region of the neural tube, is compatible with life but associated with significant morbidity, including lower limb paralysis.
T is involved in susceptibility to the development of chordoma (CHDM) [MIM:215400]. Chordomas are rare, clinically malignant tumors derived from notochordal remnants. They occur along the length of the spinal axis, predominantly in the sphenooccipital, vertebral and sacrococcygeal regions. They are characterized by slow growth, local destruction of bone, extension into adjacent soft tissues and rarely, distant metastatic spread. Note=Susceptibility to development of chordomas is due to a T gene duplication. -

Immunocytochemistry/ Immunofluorescence - Anti-Brachyury / Bry antibody (ab20680)This image is courtesy of Ludovic Valllier, University of Cambridge, UKAnti-Brachyury antibody, ab20680, stained nuclei of human embryonic stem cells differentiated into mesendoderm. As would be expected, mesoderm cells express Brachyury whereas endoderm cells are negative.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Brachyury / Bry antibody (ab20680)This image is courtesy of an Abreview submitted by Jim Manavisab20680 staining Brachyury in Human brain tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 3% serum for 30 minutes at room temperature; antigen retrieval was by heat mediation with a citrate buffer. Samples were incubated with primary antibody (1/2000 in horse serum) for 12 hours. A Streptavidin-conjugated Horse anti-rabbit monoclonal (1/250) was used as the secondary antibody. -
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Brachyury / Bry antibody (ab20680)This image is courtesy of Amanda Evans, University of CambridgeA proportion of nuclei from Day 3 Mouse EBs (derived from R1 cells) stained positive for Brachury using ab20680. In Day 8 EBs a vastly reduced proportion of nuclei stained positive (not shown). In day 10 EBs no nuclei stained Brachyury-positive. The IHC-P data for Brachyury in EBs corresponded with qRT-PCR expression data (not shown). Controls on Day 3 EBs in which primary or secondary antibody were omitted, undifferentiated ES cells and feeder cells (MEFs) all exhibited very little background staining. Zinc was used for tissue fixation. -

All lanes : Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/50000 dilution
Developed using the ECL technique.
Performed under reducing conditions.
Predicted band size: 47 kDa
Observed band size: 50 kDa why is the actual band size different from the predicted?
Exposure time: 4 minutesThis blot was produced using a 4-12% Bis-tris gel under the MOPS buffer system. The gel was run at 200V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab20680 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

Observed band size: 53 kDa why is the actual band size different from the predicted?
Additional bands at: 75 kDa. We are unsure as to the identity of these extra bands.
ab20680 recognizes a band of 53 kDa in Murine Embryonic Stem Cells differentiated to express mesoderm markers. This corresponds in size to the Brachyury protein which has a predicted molecular weight of 47 kDa. A band of 75 kDa has also been observed, although we are unsure as to the identity of this band.
