Description: This RXDMC monoclonal antibody reacts with human and mouse Runx1, which is also known as AML1. This 50-kDa transcription factor is expressed in hematopoietic cells such as myeloid, T, and B cells, but not erythroid cells. Furthermore, Runx1 can be detected in nearly all non-hematopoietic tissues except the brain and heart. Runx1 is involved in several stages of T cell development, including the CD4-CD8- double negative (DN) to CD4+CD8+ double positive (DP) transition and commitment to the CD4 lineage. In addition to its role in thymocyte development, Runx1 has also been implicated in Th2 differentiation and immune homeostasis via direct interaction with Foxp3 in CD4+CD25+ regulatory T cells. Runx1 also affects Th2 differentiation by negatively regulating Gata-3 expression. Finally, the AML1 gene, which encodes Runx1, is a frequent target of translocations in acute myeloid leukemia.
In humans, alternative splicing results in the generation of eleven isoforms. In mice, five isoforms exist as a result of alternative splicing; isoform 4 (aka AML1-C) is the most highly expressed in hematopoietic cells. Sequence analysis indicates that the RXDMC antibody recognizes isoform 4 in mouse and all human isoforms except AML-1FA, AML-1FB, and AML-1FC.
Applications Reported: This RXDMC antibody has been reported for use in intracellular staining followed by flow cytometric analysis.
Applications Tested: This RXDMC antibody has been tested by intracellular staining and flow cytometric analysis of mouse thymocytes using the Foxp3/Transcription Factor Staining Buffer Set (cat. 00-5523) and protocol. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.
Filtration: 0.2 µm post-manufacturing filtered.
RUNX1 belongs to the mammalian RUNX family of DNA binding proteins that regulate the expression of genes involved in cellular differentiation and cell cycle progression. RUNX1 is essential for hematopoietic stem cell generation in the vascular regions of the aorta, vitelline and umbilical arteries, yolk sac and placenta. RUNX1 is expressed in all tissues except brain and heart, with highest levels in thymus, bone marrow and peripheral blood.
