Anti-FLI1 Antibody

Raised in rabbit against the ETS-family transcription factor Friend Leukemia Integration 1, this polyclonal unconjugated antibody is supplied by Antibodies.com as a 100 µl vial validated for western blot and immunohistochemistry workflows on human and mouse samples. FLI1 plays central roles in megakaryocyte differentiation, platelet biogenesis, and endothelial gene regulation, and the reagent is commonly used by groups studying normal hematopoiesis, vascular biology, and the molecular pathology of Ewing sarcoma, where rearranged FLI1 loci are a defining diagnostic feature. Because the antibody is supplied unconjugated, it can be paired with a broad choice of secondary labels, including HRP, biotin, and fluorophore conjugates, supporting chromogenic IHC, immunofluorescence imaging, and chemiluminescent western blot detection in the same lab workflow. The polyclonal format offers recognition of multiple epitopes on FLI1, which can be helpful when working with partially degraded lysates or fixed tissue sections. For long-term use, aliquot the reagent upon arrival, store frozen to limit freeze-thaw cycles, and protect from light whenever a fluorescent detection step will be applied downstream.
