Figure 1From: A robust, low- to medium-throughput prnpgenotyping system in sheep Scheme of PRNP ARMS-PCR design. PrP amino acid positions are given above. The allele-specific up-primers (discrimination of A-V at codon 136) are fluorescence labelled, whereas down primers (discrimination of R-H and Q-R-H at codon 154 and 171, respectively) are of different lengths (tails are shown as red lines).Back to article page
