Modern Diagnostics A new line of AmpliChip
tests are designed to combine the power of the polymerase chain reaction (PCR) with the microarray technology.
Microarrays are the recognised standard for the massively parallel study of genes within a biological
system, including the study of gene structure and gene function. The Polymerase chain reaction is a
technique used in molecular biology to amplify a single or few copies of a piece of DNA across several
orders of magnitude, generating millions or more copies of the DNA piece.
AmpliChip
CYP 450 Test Often described as “molecular microscopes”, microarrays
are powerful diagnostic and research tools packed onto tiny glass chips no bigger than a thumbnail.
The AmpliChip CYP450 Test microarray contains more than 15’000 different oligonucleotide probes which
can analyse both sense and anti-sense strands of an amplified target DNA sample. It is Roche’s first
test to use microarray technology for comprehensive analysis of two genes that can influence drug efficacy
and adverse drug reaction. The test detects genetic variations in the Cytochrome P450 2D6 and 2C19 genes
and provides the associated predictive phenotype (poor, intermediate, extensive, or ultra-rapid metaboliser).
