Technical Information
Test Procedure: Help
PCR amplification and automated sequence analysis of the spastin (SPAST) gene exons 1 to 17. Primer sequences used for this analysis were designed by us and are available upon request. Both forward and reverse sequence analyses are performed using the Applied Biosystems Big Dye Terminator V1.1 cycle sequencing kit and … View more
