Sufficient aRNA for most microarray analyses from a
four hour in vitro transcription reaction (>500 ng
input RNA)
Labeling aRNA
Several different methods can be used to
label amplified antisense RNA (aRNA) for array analysis. Cy
dyes, other fluorophores, or biotin can be incorporated: 1)
during the in vitro transcription (IVT) step of aRNA synthesis
via modified-rNTP incorporation (direct labeling), 2) during a
subsequent reverse transcription reaction via modified-dNTP
incorporation (direct labeling), or 3) in a coupling reaction
after aRNA synthesis where the label is added to an amino
allyl-modified rNTP incorporated during IVT or reverse
transcription (indirect labeling). Increasingly, amino allyl
incorporation combined with a secondary dye coupling reaction
is being used for the generation of samples for array
