GATA1 Antibody / Hematopoietic Transcription Factor Antibody (RQ6768)

GATA1 Antibody Human Testis IHC. IHC staining of FFPE human testis with GATA1 antibody demonstrated predominantly nuclear staining in spermatogenic cells, consistent with the localization of GATA1 as a zinc finger transcription factor. GATA1 regulates gene expression programs involved in hematopoietic differentiation and has also been implicated in Sertoli cell function and normal testicular development. The nuclear staining pattern reflects its role in transcriptional regulation. HIER was performed by boiling tissue sections in pH 8 EDTA buffer for 20 minutes followed by cooling prior to staining. These results support the utility of GATA1 Antibody for studies of transcriptional regulation, hematopoietic biology, reproductive biology, and developmental biology.

GATA1 Antibody Human K562 FACS. Flow cytometric analysis of human K562 cells using GATA1 antibody demonstrated a clear rightward shift in fluorescence intensity (blue) compared with the isotype control (green) and unstained cells (red), indicating specific detection of intracellular GATA1 expression. GATA1 is a zinc finger transcription factor that serves as a master regulator of erythropoiesis by controlling genes required for erythroid lineage commitment, hemoglobin synthesis, and red blood cell maturation. K562 cells, an erythroleukemia cell line, express GATA1 and are widely used as a model for erythroid differentiation and hematopoietic gene regulation. Cells were incubated with GATA1 antibody at 1 ug/million cells following goat serum blocking. These results support the utility of GATA1 Antibody for flow cytometric studies of hematopoiesis, erythropoiesis, hematopoietic transcriptional regulation, and leukemia research.

GATA1 Antibody Human K562 and Mouse Testis WB. Western blot analysis of GATA1 expression was performed using anti-GATA1 antibody. Lane 1: human K562 cell lysate. Lane 2: mouse testis tissue lysate. GATA1 is a zinc finger transcription factor that serves as a master regulator of erythropoiesis by controlling genes required for erythroid lineage commitment, hemoglobin synthesis, and red blood cell maturation. In addition to its essential role in hematopoietic development, GATA1 is expressed in Sertoli cells and contributes to normal testicular function. Specific immunoreactive bands are detected at approximately 43 kDa in both samples, consistent with the predicted molecular weight of GATA1. These results support the utility of GATA1 Antibody for studies of hematopoiesis, transcriptional regulation, reproductive biology, and developmental biology.
