This document provides information about TaqMan Gene Expression Assay products from Applied Biosystems. It offers pre-designed probe and primer sets (TaqMan Gene Expression Assays) for quantifying gene expression in common model organisms like human, mouse, rat, Arabidopsis, and Drosophila. It also describes options for custom assays with user-designed sequences. The assays use TaqMan chemistry and real-time PCR for sensitive and reproducible gene expression analysis.

human, mouse, rat, Arabidopsis, or

consists of three main steps:
Step One
Both public and Celera sequence data are
used to identify the optimal probe and
primer locations. This process consists of:
• Mapping transcripts to the genome
to identify exon boundaries
• Masking sequence discrepancies
between public and Celera data
• Masking sequence repeats The Applied Biosystems online catalog map view graphically represents the assay’s physical location on the gene, and
which transcript(s) each assay detects.
