This antibody is intended for in vitro diagnostic (IVD) use.
Ventana Medical Systems' CONFIRM anti-Topoisomerase IIα (JS5B4) Rabbit Monoclonal Primary Antibody is designed to qualitatively detect the presence of topoisomerase IIα expressing cells via light microscopy in formalin-fixed, paraffin-embedded tissue following staining on a Ventana BenchMark XT instrument. During the cell cycle, topoisomerase IIα is expressed in the G1, S, G2, and M phase but is absent in the G0 (quiescent) phase.1 Assessment of the proportion of positive staining cells for topoisomerase IIα may aid in evaluation of the proliferative activity of normal and/or neoplastic tissue.2,3,4 The clinical interpretation of any staining, or the absence of staining, must be complemented by morphological studies and evaluation of proper controls. Evaluation must be made by a qualified pathologist within the context of the patient’s clinical history and other diagnostic tests.
