Biological Roles

Target overview (literature)

• Brachyury (Bry, T) is a T-box family transcription factor central to mesoderm specification, notochord formation, and early gastrulation in vertebrate embryogenesis.
• It regulates genes involved in cell movement and differentiation during early development. Expression is tightly timed/spatially restricted and is a canonical marker of mesodermal lineage commitment in pluripotent stem cell differentiation protocols.

Research relevance

• Brachyury expression serves as a readout for directed differentiation of human ESCs/iPSCs toward mesodermal fates. It is also used to map developmental trajectories and construct gene regulatory networks in early embryos across species.
• In adult/pathological contexts, altered Brachyury expression has been observed in certain tissues in the literature; researchers investigate its roles in epithelial–mesenchymal transitions and lineage plasticity. No clinical or therapeutic claims are made here.

Antibody utility

• An anti-Brachyury mAb enables selective detection of nuclear Brachyury protein in fixed cells/tissues or cell lysates, supporting temporal and spatial expression profiling.

Item-specific note

• Epitope region, isotype, species reactivity, and cross-reactivity for Recombinant Brachyury/Bry mAb (Ab091590) are not specified for this item; refer to the CoA/Spec Sheet for target-binding particulars and validated species.

Buffer Applications

Applicability note

• This is an antibody reagent; it is used within biological buffer systems rather than acting as a buffering agent itself.

General guidance (literature)

• Common working buffers: PBS or TBS at pH ~7.2–7.6. Additives such as 0.05% Tween-20 can reduce nonspecific binding in wash steps.
• Blocking solutions: 5% serum (species-appropriate), BSA (1–5%), or casein-based blockers to minimize background.
• For IHC, antigen retrieval buffers (e.g., citrate pH ~6, Tris-EDTA pH ~9) may be used depending on fixation and tissue; optimize empirically for nuclear antigens like Brachyury.
• For WB, transfer and blocking buffers should be optimized to preserve epitope integrity; inclusion of mild detergents can aid specificity.

Item-specific note

• The supplied storage buffer, recommended working dilution buffer, and compatibility specifics for SKU Ab091590 are not specified for this item; please consult the CoA/Spec Sheet.

Green Alternatives

Applicability note
