1. EAS FISH for EBV EBER1 is Sensitive to Prior RNase treatment
JY(LCL), Epstein-Barr Virus transformed B cells, were probed with an antisense probe for EBER1 (filled
histograms) or with a nonsense probe (open histograms). The probes were detected by fluorescence in
situ hybridization (FISH) or by FISH with enzymatic amplification staining (EAS). The JY(LCL) cells shown
in the right panel were treated with RNase prior to hybridization.
These results demonstrate that EAS FISH is sensitive to prior RNase treatment.
