Polycomb & Trithorax复合物靶基因基因表达PCR芯片可以同时检测被Polycomb &Trithorax复合物调控的84个关键基因的表达。 Polycomb &Trithorax复合物的活性控制着胚胎多能干细胞分化机制的诱导。它们活性的失调造成细胞特性改变，细胞分化和增殖基因的错误表达，并促成肿瘤发生。利用该芯片，研究者可以方便并且可信地研究对被Polycomb和Trithorax复合物调控的重要靶基因进行同时检测。Cellular Mechanisms: Differentiation: BMP2, CADM1 (TSLC1), CCND2,CHST11, DHH, DKK1, EFNB1, EPHA4, EPHB3, FOXA2 (HNF3B), GATA2, GATA6,HAND1, HES1, IL6R, IRX3, JUN, KLF4, OTX2, PDGFRA, PMP22, RARB, SALL1,SOX17, THPO, TRIM10, TRIM15, UCP1, WNT5A.
