Overview
It is necessary to remove excess primers and unincorporated nucleotides from the PCR reaction prior to sequencing. An enzymatic cleanup method offers precision and speed over technologies such as spin columns or beads. ExoSAP-IT Express reagent consists of two hydrolytic enzymes, a modified Exonuclease I and Shrimp Alkaline Phosphatase (SAP), in a specially formulated buffer. It is used to remove excess primers and dNTPs from a PCR mixture with no interference in downstream applications. This unique, highly stable, one tube solution allows for greater confidence and superior sequencing results (Fig. 1).

Innovative solution
Affymetrix scientists engineered Exonuclease I to have increased heat lability, allowing for inactivation in only 1 minute (Fig. 2). ExoSAP-IT Express reagent is added directly to the PCR product for a 4 minute cleanup at 37°C, followed by a 1 minute inactivation at 80°C, which provides accurate and consistent results in just 5 minutes.

Fastest PCR cleanup method
This novel technology allows for a significant reduction in sample cleanup time with minimal steps, providing the simplest workflow (Fig. 3). ExoSAP-IT Express reagent offers rapid turnaround times and improved efficiency of resources while delivering the quality that scientists have become accustomed to when using ExoSAP-IT for PCR product cleanup.

Optional tracking dye
ExoSAP-IT Express reagent is also available premixed with a tracking dye for added convenience. This inert, blue color dye
offers visual confirmation that the reagent has been added to samples for PCR cleanup during the pipetting process. The dye does not interfere with downstream applications such as subsequent PCR and sequencing.

Conserve PCR samples — simple one step, 100% recovery
The ExoSAP-IT Express enzymatic cleanup method is designed to minimize errors by reducing your protocol to a single pipette step, allowing for automated or manual processing from a single tube or microtiter well. ExoSAP-IT Express reagent outperforms the competition by ensuring 100% recovery of all amplicon sizes, both short and long (Table 1).

ExoSAP-IT Express PCR Product Cleanup is active in commonly used PCR buffers, so no buffer exchange is required. After treatment, ExoSAP-IT Express reagent is inactivated by heating at 80°C for 1 minute. The treated PCR products are then ready for subsequent analysis in applications that require DNA to be free of excess primers and nucleotides.

ExoSAP-IT™ PCR Product Cleanup Reagent (Applied Biosystems™)

ExoSAP-IT™ PCR Product Cleanup Reagent is used for enzymatic cleanup of amplified PCR product. It hydrolyzes excess primers and nucleotides in a single step. ExoSAP-IT-purified samples are ready for use in downstream applications such as DNA sequencing or single nucleotide polymorphism (SNP) analysis.

• Remove excess primers and unincorporated nucleotides enzymatically
• Prepare DNA sequencing samples with one pipetting step
• Conserve precious PCR products with up to 100% recovery
• Minimize column cleanup and sample loss

The ExoSAP-IT one-step solution provides a simple way to enzymatically purify a PCR reaction. The reaction setup is complete with one pipetting step, which is followed by two incubations. The first incubation digests excess primer and dephosphorylates nucleotides. The second, high-temperature incubation inactivates the enzymes.

Enzymatic cleanup is a very efficient method for PCR purification. Adding ExoSAP-IT reagent directly to the PCR product eliminates transfer steps to tubes, wells, or columns and conserves PCR amplicons, helping reduce the chance of cross contamination; no further processing needed.

After enzymatic cleanup with ExoSAP-IT reagent, primers and dNTPs will no longer interfere with DNA sequencing or SNP analysis.

HT ExoSAP-IT™ High-Throughput PCR Product Cleanup (Applied Biosystems™)

HT ExoSAP-IT High-Throughput PCR Product Cleanup is an alternative formulation of ExoSAP-IT reagent specifically designed for the unique requirements of high-throughput, automated platforms, and multi-channel pipettes. HT ExoSAP-IT reagent has both a longer lifetime at higher temperatures and a decreased viscosity for robotic pipetting.

Like ExoSAP-IT for PCR Product Cleanup (PN 78200), HT ExoSAP-IT reagent is a mixture of Exonuclease I and Shrimp Alkaline Phosphatase (SAP) which removes excess primers and dNTPs following a PCR reaction in a single incubation. HT ExoSAP-IT reagent possesses greater thermal stability and lower viscosity which provides greater ease-of-use in automated 96- and 384-well formats.

Convenient packaging — Available in 8-tube strips and 12 strips in a 96-well plate
Stable at +25deg;C for 8 hours — Retains full functional activity and at 45°C is stable for one week

HT ExoSAP-IT reagent is added directly to the PCR product and incubated at 37°C for 15 minutes. After PCR treatment, it is inactivated simply by heating to 80°C for 15 minutes. Our high-throughput formulation is designed for robotic pipetting and multi-channel pipettes. HT ExoSAP-IT reagent has a lower viscosity than the standard mix and is available in an 8-tube strip format for ease of use.

HT ExoSAP-IT reagent utilizes two hydrolytic enzymes, Exonuclease I and SAP, together in a specially formulated buffer, to remove unwanted dNTPs and primers from PCR products. Exonuclease I removes residual single-stranded primers and any extraneous single-stranded DNA produced in the PCR. SAP removes the remaining dNTPs from the PCR mixture.

Simple: Single-step
HT ExoSAP-IT reagent requires only one pipetting step and two incubations. Just add HT ExoSAP-IT reagent to the PCR product and within 30 minutes sequencing, SNP analysis, single base extension, or fragment analysis can be performed. Enzymatic removal of excess primers and unincorporated nucleotides occurs in one easy step by using HT ExoSAP-IT reagent in a single tube, 8-tube strip, or 12 strips in a 96-well low skirted PCR plate. Our new formatting makes this an ideal product for use with robotics.

Exceptional accuracy with HT ExoSAP-IT
Achieve high data quality and sequencing accuracy with HT ExoSAP-IT, even with long read lengths. Sequence reads of PCR products treated with HT ExoSAP-IT were on average 50+ bases longer than samples treated with competitor products. Using human genomic DNA, a 1007 bp fragment was sequenced with no miscalls. The size limitations associated with alternative PCR cleanup methods are not a factor with HT ExoSAP-IT. Phred 20 values over the entire length of a 970 bp sequence was 822 ± 9 with HT ExoSAP-IT-treated samples and only 776 ± 83 with samples treated with Agencourt™ AMPure™ XP.

No sample loss
Use of HT ExoSAP-IT eliminates all gel or column purifications, sedimentations, filtrations, beads, and/or magnetic separations(1). There is 100% recovery of both short and long PCR products with HT ExoSAP-IT.

HT ExoSAP-IT-treated PCR product is stable
Ht ExoSAP-IT reagent is rigorously tested and subject to strict quality control. No product degradation occurred after storage of HT ExoSAP-IT treated PCR product for one week at 24°C.
