[BioC] ULYSIS Alexa Fluor labelling kit / dye bias / limma

Hi,

Quick question this time. Basically these dyes have higher intensity,
less quenching and correlate more between dye pairs. The ULYSIS kit uses
chemical labelling which eliminates sequence effects.

As far as I know Limma accounts for dye bias during normalisation. If
there is less/no bias will there be artifacts introduced? Or other
points I need to be aware of?

Thanks,
Matt
