The stringent quality control (QC) and quality assurance (QA) measures are listed in the table below:
| QA/QC steps for StaRT-PCR*** reagents |
| Reagent | QC/QA Test | Acceptable Specifications |
| Individual primer pairs |
Correct sequence and amount |
COA from manufacturer |
| Specificity |
BLAST search of primer sequence verified to be 100% correct. No hit with non-specific targets. |
| Correct amplimer size verified for both internal standard and native template |
| Primer sequences of internal standard verified to be 100% correct by sequence analysis |
| Lack of SNP interference |
Primer sequences devoid of known SNPs |
| Discrimination of alternative transcripts |
Primers designed to allow for differentiation of alternative transcripts |
| Primer stock solutions |
PCR with no template |
Free from Internal Standard or native template contamination |
| Primer stock solutions/IS* |
PCR with IS only |
Correct size IS amplimer |
| No interfering products |
| Internal Standard* |
Concentration of each internal standard determined by standard method |
Each internal standard quantified using the Hoechst dye method with a calf thymus DNA standard |
| Primer stock solutions/IS*/SMIS** |
Lower limit of detection |
Amplimer from 60 molecules or less of template |
| SMIS |
PCR with SMIS� only |
Correct size IS for each assay |
| No native template contamination |
| Functional test: StaRT-PCR� with Universal Human RNA |
Correct native template and Internal Standard amplimer produced, assay characteristics acceptable |
Pipettes, hoods, fluorometer, thermocycler blocks all on a routine calibration/maintenance schedule
* Internal Standard
** Standardized Mixtures of Internal Standards (SMIS).
*** "StaRT-PCR" - Standardized (Sta), Reverse Transcriptase (RT), Polymerase Chain Reaction (PCR) - PCR is an enzymatic process to increase the number of copies of DNA for easier detection.
