This product is used to dilute template DNA or RNA when preparing serial dilutions of the standard for establishing the standard curve in real time PCR. When template DNA and RNA are diluted with sterilized water or TE buffer, they may stick to the inside of the tube which can prevent correct dilution. This product helps to avoid this absorption and allows correct dilutions at lower concentrations. In addition, this product is RNA free, and will not contain non-specific amplification derived from RNA.
