Fig. 2From: A formalin-free method for stabilizing cells for nucleic acid amplification, hybridization and next-generation sequencingDNA hybridization assayed by ERBB2 (HER-2/neu) FISH. SKBR-3 cells were snap frozen (a) or exposed to 10 % NBF (b) or SCP (c) prior to FISH analysis. Representative cell nuclei are shown for HER-2 amplification (green) and multiple copies of CEP17 (red), as well as countstain with DAPI (blue). n = 5Back to article page
