Test Procedure: Help
PCR amplification and automated sequence analysis of the myelin protein zero (MPZ) exons 1 to 6. The primer sequences used for this analysis are described by Nelis et al (1994). Both forward and reverse sequence analyses are performed using the Applied Biosystems Big Dye Terminator V1.1 cycle sequencing kit and … View more
