the Duplica ApoE Genotyping Kit is an in vitro nucleic acid amplification test for the qualitative detection of ApoE human gene alleles such as: ApoE*E2 (Cys112-Cys158), ApoE*E3 (Cys112-Arg158) and ApoE*E4 (Arg112-Arg158), in human genomic DNA extracted from peripheral whole blood samples collected in EDTA.
