"If you have access to a real-time PCR
instrument, you can use PCR Arrays"
Profiler™ PCR Arrays are the most reliable and sensitive gene
expression profiling technology for analyzing a panel of genes in
signal transduction pathways, biological process or disease related
gene networks. The PCR Arrays can be used for research on cancer,
immunology, stem cells, toxicology, biomarker discovery and validation,
and phenotypic analysis of cells and transgenic animals. See the complete
list of PCR Arrays.
You can use any 96-well or 384-well
real-time PCR instrument. See

How it Works
The PCR array is a set of optimized
real-time PCR primer assays on 96-well or
384-well plates for pathway or disease focused genes as well as
quality controls. The PCR array performs gene expression analysis with
sensitivity and the multi-gene profiling capability of a microarray.
