ExoSAP-IT™ PCR Product Cleanup Reagent

The HT ExoSAP-IT Fast High-Throughput PCR Product Cleanup reagent is designed for automated handlers as it has a lower viscosity than standard ExoSAP-IT PCR Product Cleanup reagent, which contains some glycerol.

The Quant-iT PicoGreen dsDNA Assay Kit is recommended for quantifying PCR products that have been cleaned with ExoSAP-IT reagent. ExoSAP-IT PCR cleanup results in 100% recovery regardless of amplicon length, and if the PCR product was quantified prior to ExoSAP-IT cleanup, additional quantification is not necessary. We do not recommend using a spectrophotometer as degraded products will be included in the quantification.

For use with reverse transcription, ExoSAP-IT does not degrade the DNA-RNA hybrid. However, it will degrade single-stranded cDNA if a 3' -OH end is present.

The tracking dyes used in the DreamTaq Hot Start Green PCR Master Mix have not been shown to interfere with functionality of the ExoSAP-IT cleanup reagents.

The proofreading function of HiFi DNA polymerases can cause partial degradation of PCR products during extended incubation at 80°C. ExoSAP-IT Express reagent is recommended for HiFi PCR cleanup because it only requires 1 minute at 80°C for inactivation.
