Figure 3From: Single-cell copy number variation detectionMA plot of a single EBV-transformed cell. (a-c) MA plot for EBV-transformed single lymphoblastoid cell 1162 before normalization (a), genomic DNA before normalization (b), EBV-transformed single lymphoblastoid 1162 after channel standardization (c). The red line represents a lowess curve fitted to the data. Note that after normalizations, most of the log2 ratio values are distributed randomly around zero.Back to article page
