How should I store cDNA produced using Omniscript Reverse Transcriptase?
FAQ ID -561

We recommend to store the cDNA at -20°C in aliquots to avoid repeated freeze/thaw cyles. If the cDNA requires dilution, we recommend to dilute it in Tris buffer, pH 8.0. Avoid storing the aliquots at high dilutions. If possible, use siliconized tubes for storage of cDNA dilutions to avoid adsorption of nucleic acids to the tube walls.
