The GenomeLab™ GeXP Genetic Analysis System is a quantitative, high-throughput, multiplexed gene expression profiling solution, it has a capacity to analyze up to 30 genes/reaction/well with unrivaled sensitivity. The GeXP can quantitatively detect small, biologically relevant changes in gene expression, as low as 0.5 fold, with high accuracy. The GeXP platform is scalable, enabling the monitoring of tens to hundreds of genes for up to tens of thousands of samples. The readout can be efficiently used to look at focused sets of genes using very small amounts, as little as 5-50 ng of total RNA, accommodating varied quality of RNA. The GenomeLab™ GeXP is also a fully automated, high-throughput sequencing and genotyping/fragment analysis system. In a single setup with one gel and one capillary array within the same plate, short templates are sequenced rapidly, long templates are sequenced faster with high quality reads, DNA fragments are sized accurately, and analyzed quantitatively with high-sensitivity and reproducibility.
