Normalization: What is it?

•This feature normailzes

signal variations associated

with instrument, capillary

array, sample salt load, and

injection variability among

capillaries and instruments

•Normalization can be

applied during primary

analysis of the data

Before normalization After normalization

HID Validation:

The 3500 Series Genetic Analyzers

•Normalization Target (NT)

•The expected average RFU for eleven peaks in the

GeneScan 600 LIZ®v2 size standard used for normalization

•Normalization Factor

•Normalization Target divided by the Average peak height of

the subset of peaks in the GeneScan 600 LIZ®v2 size

standard used for normalization

•Normalization Factor Threshold

•The passing range for Normalization Factor (default range is

0.3 to 3.0)
