Why is the Type-it Mutation Detect PCR Kit recommended for preamplification of SNPs?

Preamplification of SNPs in preparation for genotyping systems like Applied Biosytem's SNaPshot requires single PCRs to be amplified and pooled, before input into this system. Using the Type-it Mutation Detect PCR Kit, all fragments can be obtained at once saving time and costs. Please follow the protocol 'Amplification of Mutations (Detection on Agarose Gels or the QIAxcel System or Agilent 2100 Bioanalyzer)' in the Type-it Mutation Detect Handbook.
