Custom RT2 PreAMP Pathway Primer Mixes

For amplification of cDNA templates prior to analysis on Custom RT² Profiler PCR Arrays

  • Custom primer mixes for human, mouse, and rat
  • Minimal hands-on time
  • Robust performance on small samples

RT² PreAMP cDNA Synthesis Kit and RT² PreAMP Pathway Primer Mixes are a novel technology enabling gene expression analysis using as little as 1 ng total RNA. A  proprietary amplification process increases the amount of cDNA for subsequent PCR array analysis. Starting sample types include fine needle biopsy and laser captured microdissection samples, stem cell clusters or embryoid bodies, and fluorescence-activated cell sorter (FACS) generated cells. Specially designed primer mixes are available for human, mouse, or rat Custom RT² Profiler PCR Arrays.

Product Details

Performance
Increased positive call rate and unbiased amplification for unbiased results

More genes are detected after preamplification using the RT² PreAMP Pathway Primer Mix (see figure "Increased positive call rate").The amplification process is unbiased, resulting in highly comparable ΔCT values between preamplified and unamplified cDNA, as evaluated by regression analysis (see figure "Unbiased amplification process").

There is a high correlation of gene expression fold change results between preamplified and unamplified samples (see figure "Faithfully amplified biology").

Principle
RT² PreAMP technology utilizes multiplex tandem PCR to preamplify gene-specific cDNA with minimal bias. Following standard revese transcription, an RT2 PreAMP Pathway Primer Mix is used to amplify templates and enable gene expression analysis on up to 4 different Custom RT2 Profiler PCR Arrays (see flowchart "Simple template amplification and gene expression analysis").

Procedure

First strand cDNA is first synthesized from up to 48 different RNA samples using the RT2 PreAMP cDNA Synthesis Kit. The cDNA is then preamplified for a custom gene list. Each first strand cDNA synthesis reaction can be amplified using up to 4 different Custom RT2 PreAMP Pathway Primer Mixes, allowing gene expression analysis on up to 4 different custom PCR arrays. The Side Reaction Reducer included in the RT2 PreAMP cDNA Synthesis Kit eliminates the residual primers from preamplification, enabling accurate detection on RT2 Profiler PCR Arrays. To complete the PCR array procedure, preamplified templates are mixed with an instrument-specific, ready-to-use RT² SYBR® Green Mastermix. 

Applications
cDNA templates generated using the Custom RT2 PreAMP cDNA Synthesis Kit in conjunction with RT2 PreAMP Pathway Primer Mixes are ready for gene expression profiling using Custom RT² Profiler PCR Arrays.
