The LabChip Dx utilizes microfluidics technology to perform reproducible, high-resolution, electrophoretic separations for analyzing multiplex PCR products. The LabChip Dx system is for use by clinical research laboratories developing molecular diagnostic tests. The platform enables simultaneous analysis of up to ten different analytes in a single sample. The LabChip Dx is also capable of analyzing large numbers of multiplex samples using minimal sample volume, and there is no need to further purify or dilute diagnostic PCR products. The new system includes specific identification, scoring, and reporting software.
