Introduction
About Primer
Express
®
Software
Primer Express software is a primer and probe design tool made specifically for use with
the following instruments:
• Applied Biosystems 7900HT Fast Real-Time PCR System
• Applied Biosystems 7500 Fast Real-Time PCR System
• Applied Biosystems 7500 Real-Time PCR System
• Applied Biosystems 7300 Real-Time PCR System
Primer Express software lets you independently design oligonucleotides (oligos) for
PCR applications using a customized application specific document for each of the
following assay types:
• Absolute/Relative Quantification
• Allelic Discrimination
When using Primer Express software, keep in mind the Applied Biosystems Rapid
Assay Development Guidelines that contain the following important components:
• Design of primers and probes using Primer Express software
• Selection of the appropriate reagent configuration (TaqMan
®
Universal PCR
Master Mix or SYBR
®
Green PCR Master Mix)
• Use of universal thermal cycling parameters
• Use of default primer and probe concentrations (or optimizing, if necessary)
IMPORTANT! These components provide a rapid and reliable system for assay design
and optimization only when used in their entirety. Due to the interdependence of many of
the individual components, the system must be adopted as a whole in order to achieve
the highest level of success.
Terms You Need
to Know
Allelic Discrimination Assay – An assay that discriminates between two alleles of
single nucleotide polymorphisms (SNPs). TaqMan
®
allelic discrimination assays use
two probes specific for the two possible SNP variants.
Anti-Sense Strand – In double-stranded DNA, the strand that does not code for the
RNA, and is not translated into proteins. Also referred to as anti-coding, negative, or
reverse strand. The Primer Express Software designs primers and probes using the sense
strand, not the anti-sense strand.
Document – In the Primer Express Software, a container used to hold sequences,
generate candidate primer and probe designs, and order candidate primer and probe
designs. The four document types available are TaqMan MGB Quantification, TaqMan
Quantification, TaqMan MGB Allelic Discrimination, and TaqMan Allelic
Discrimination.
