Thaw all components (except the enzyme/buffer mix), mix thoroughly and centrifuge before use.

Add the following to a 0.2mL thin-walled PCR tube sitting on ice:

cDNA Synthesis by Reverse Transcription

Component	Volume
RNA (40ng – 10ng to 1μg total RNA/rxn)	variable
Nuclease free water	variable
qScript cDNA synthesis mix	4 uL
Final Volume	20 uL

Thaw all components (except enzyme), mix thoroughly and centrifuge before use.

Mix components by gently vortexing and then centrifuge 4s to collect contents.

Incubate in a PCR machine using the following conditions:

5 min at 25°C

30 min at 42°C

5 min at 85°C

Hold at 4°C

After completion of cDNA synthesis, us 1/20th of the first-strand reaction (2-4μL) for PCR amplification in water. Also do 2,3, and 4-fold dilutions of each sample to ensure that the PCRs will be within the primer linear range. Do 3 replicates of each PCR reaction. Run PCRs on a real-time PCR machine (e.g. ABI 7900).
