Lane and Band Table Measurement Definitions
This section defines the measurements that display in the Lane and Band tab in the
Analysis table. Use the Data display options button to choose the columns to
display.
Band Number — each band in a lane has a unique number, sorted from top to
bottom.
Band Label — you can assign a custom label to each band by clicking the Band
Label field of the Lane and Band table.
Molecular Weight — the molecular weight of the band is calculated based on the
user-defined standard and regression method. Italic values indicate extrapolated
values. When using nucleic acid gels, the size of the band is displayed in base pairs.
Relative Front — values between 0–1 indicate the relative movement of the band
from top to bottom.
Volume — the sum of all intensities within the band boundaries.
Abs. Quant. — absolute quantification of the band.
Rel. Quant. — relative quantification of the band compared to the reference band.
Band % — percentage of the band’s volume compared to all band volumes in the
lane.
Lane % — percentage of the band’s volume compared to the entire volume of the
lane.
Volume Measurement Definitions
This section defines the measurements that display in the Volume tab in the Analysis
table. Use the Display Data Options button to choose the columns to display.
Volume Number — a unique number is assigned to each volume.
Volume Label — software-generated labels for different types of volumes
(U – unknown, B – background, S – standard). Label can be changed in Volume
