• Highest expression. Scale the normalized gene expression to the highest for each
target by dividing the expression level of each sample by the highest level of expression
in all the samples. This scaling option uses the scaled to highest formula
• Lowest expression. Recalculate the normalized gene expression for each target by
dividing the expression level of each sample by the lowest level of expression in all the
samples. This scaling options uses the scaled to lowest formula

• Standard Error of the Mean (default, SEMs)
• Standard Deviation (Std Devs)

ULTIPLIER
Select a multiplier for the error bars in the Gene Expression graph. Select one of these
integers: +/- 1 (default), 2, or 3. The type of multiplier changes when you select the Error Type:
• SEMs for Standard Error of the Mean
• Std Devs for Standard Deviations

Open this window whenever more than 1 reference gene is used. The software calculates two
quality parameters for the reference genes:
• Coefficient of Variation (CV) of normalized reference gene relative quantities. Lower
CV values denotes higher stability
• M-value . A measure of the reference gene expression stability
