Fig. 4From: Microarray detection method for pathogen genes by on-chip signal amplification using terminal deoxynucleotidyl transferaseA Grey capture images of array spots formed on the COC chip to detect four pathogenic genes. Scale bar is 4 mm. B Bar graph of the grey values of (A) images analyzed using Image J software. The symbol (− or +) indicates the amount of each pathogen (0 or 105 cells)Back to article page
