Anchor primer associated problems in differential display reverse transcription polymerase chain reaction

Chen, Yihua and Wang, Bin and Weining, Song and Daggard, Grant (2004) Anchor primer associated problems in differential display reverse transcription polymerase chain reaction. Analytical Biochemistry, 329 (1). pp. 145-147. ISSN 0003-2697


Differential display reverse transcription PCR
(DDRT-PCR)2 was first reported by P. Liang and A.B.
Paredee in 1992. The method utilized an anchor
primer, including a poly(T) component with the addition
of one or two select bases in reverse transcription.
The first-strand cDNA was amplified via PCR using the
same anchor primer and a 10-base random primer. As
the DDRT-PCR method is simple and sensitive, it has
become a popular technology in gene expression work.
However, a major problem with the technique is its ability
to produce a high rate of false-positive products. A
number of approaches to overcome such problems have
been suggested, including using improved gel resolution
systems, performing PCR with the cDNA generated
by two different reverse transcriptases, and using cytoplasmic RNA to avoid unprocessed mRNA.
While there has been a focus in the literature on modification of the random primer component as a means of improving DDRT-PCR reliability, in this study we report on the impact of modifications to the traditional anchor primer
component and the role of anchor primers.
The addition of weight bases is important for improving the reliability of traditional anchor primer in the DDRT PCR condition and can contribute to the reproducibility of DDRT PCR products.
