The One-Cycle cDNA Synthesis Kit contains all necessary reagents (see the following table) to carry out the cDNA synthesis reaction for thirty samples in a "standard" assay for GeneChip arrays. From total RNA starting materials (1 μg to 15 μg), using this kit, sufficient double-stranded cDNA can be synthesized, purified on the cDNA Cleanup Column, and used as template in the subsequent in vitro transcription labeling reaction.
