Predicted Molecular Wt: 174kDa Purity: ProA affinity purified IgG Species Cross-reactivity: Human Form: Liquid Applications: IHC-P Swissprot ID: P11388
Background: The topoisomerase II-α isoformisa 170 kDa nuclear protein and plays an important role in DNA synthesis and RNA transcription, as well as chromosomal segregation during mitosis.
Topoisomerase II-α is reported to be a sensitive and specific marker of late S-, G2- & M-phases in transformed and developmentally regulated normal cells, and has been shown to be over-expressed in many human cancers.
Decreased expression of Topoisomerase II-α is the predominant mechanism of resistance to several chemotherapeutic agents.
Subcellular location: Nucleus Recommended method: Heat induced epitope retrieval with Tris-EDTA buffer (pH 9.0), primary antibody incubate at RT (18°C-25°C) for 30 minutes. Immunogen: Synthetic peptide corresponding to Topo II α residues within aa1431-1531 of Topo II α was used as an immunogen. Storage Buffer: PBS 59%, Sodium azide 0.01%, Glycerol 40%, BSA 0.05%. Storage conditions: -25°C to -18°C Storage instructions: Shipped on blue ice. Upon delivery, aliquot, and store at -25°C to -18°C. Avoid freeze / thaw cycles. Recommended Dilutions: IHC-P: 1:100-1:200 Background References: 1. Lynch BJ, et al, Hum Pathol. 1997 Oct;28(10):1180-8. 2. Gupta D, et al,Appl Immunohistochem Mol Morphol. 2001 Sep;9(3):215-21.
