Anti-GATA3 Antibody [KT63]

The KT63 clone is a rat IgG2a monoclonal antibody that recognizes the GATA3 transcription factor, a zinc-finger DNA-binding protein involved in T-helper 2 lymphocyte commitment, mammary gland morphogenesis, and luminal epithelial identity. Distributed by Antibodies.com as a 100 µg unconjugated liquid preparation, the reagent is validated for western blot and immunofluorescence assays and reacts specifically with mouse GATA3, with cross-reactivity not established against human or rat orthologs. Because GATA3 serves as a clinically relevant nuclear marker for luminal breast carcinoma and urothelial cancer subtyping, this reagent is widely applied in immunology, developmental biology, and tumor pathology research. For best stability, aliquot upon receipt, avoid repeated freeze-thaw cycles, and store frozen at -20 °C in working aliquots; short-term handling at 2 to 8 °C is acceptable for daily use.
