Splet09. okt. 2003 · As demonstrated in this study, the level of a particular RNA may be reliably determined by RT-PCR even in a total RNA that is usually considered as degraded (28S to 18S ratio as low as 0.4), provided that random primer is used in RT. In contrast, the use of the oligo (dT) primer in RT-PCR may lead to underestimation of specific mRNA level in ... http://www.cycloudbio.com/m5/product/41353.html
