Diagram of CLONTECH's amplification of cDNA through the use of SMART RACE.

    The SMART RACE cDNA Amplification Kit is the latest technology in cDNA amplification (PCR).  SMART stands for Switching Mechanism At 5' end of RNA Transcript.  This mechanism is what allows the 5' end to be more efficiently and successfully amplified resulting in SMART RACE's ability to amplify cDNA with the 5' end and therefore longer than the cDNA amplified using the previous RACE technology.  A sizeable problem resulting from the use of RACE technology is that of excessive background.  Because RACE needs more starting material from which to amplify the cDNA, researchers using this technique are forced to use total RNA instead of the mRNA.  Therefore, cDNA is amplified in small quantities from the total RNA as well as the mRNA included and background noise results.
