Figure 1From: Sequence analysis of Drd2, Drd4, and Dat1 in SHR and WKY rat strainsPCR amplification of Dat1 exon 3 using three alternative primer pairs on SHR (S) and WKY (W) DNA. On WKY DNA the reaction did not work using primer set (a) and resulted in a smaller PCR product than seen using SHR DNA with sets (b) and (c).Back to article page
