GATA Binding Protein 1 Antibody / GATA1 Antibody (R33371)

GATA Binding Protein 1 Antibody Human PBMC WB. Western blot analysis of GATA1 expression was performed using anti-GATA1 antibody on human peripheral blood mononuclear cell (PBMC) lysate. A specific immunoreactive band is detected at approximately 43 kDa, consistent with the predicted molecular weight of GATA1. 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. Although GATA1 expression is primarily associated with erythroid and megakaryocytic lineages, its detection in PBMC lysate reflects the presence of hematopoietic cell populations expressing this lineage-specific transcription factor. These results support the utility of GATA Binding Protein 1 Antibody for studies of hematopoiesis, erythropoiesis, hematopoietic transcriptional regulation, and blood cell differentiation.
