The ChargeSwitch™ gDNA Normalized Buccal Cell Kit uses magnetic bead-based technology to allow rapid and efficient isolation of genomic DNA from human buccal swabs in less than 15 minutes after lysate preparation.

• Optimized for higher-purity DNA extraction
• Ideal for STR profiling
• Compatible with high-throughput protocols

Rapid Purification Protocol
The ChargeSwitch™ gDNA Normalized Buccal Cell Kit allows purification of genomic DNA from human buccal cell swabs or pelleted cells from a mouthwash in less than 15 minutes after lysates preparation. ChargeSwitch™ gDNA Normalized Buccal Cell Kit uses magnetic beads with a unique, ionizable functional group whose affinity for nucleic acids is pH-dependent to facilitate nucleic acid purification. High-quality genomic DNA is purified at a normalized concentration of 1-3 ng/μL in a total volume of 150 μL (Figure 1) by eliminating the need for lengthy quantitation and dilution steps. Samples can be stored for up to 2 weeks at 4°C before processing without a noticeable loss in DNA yield or quality.

Note: DNA yield varies and is dependent on several factors including the technique of the person taking the swab, whether the donor is a high or low shedder, and the type of swab used.

Validated for Single Tandem Repeat (STR) Profiling
After employing the ChargeSwitch™ gDNA Normalized Buccal Cell Kit, purified gDNA is suitable for use in STR analysis of poor or environmentally degraded samples, and for downstream applications such as PCR.

Compatible with Single Tube and High-Throughput Protocols
The ChargeSwitch™ gDNA Normalized Buccal Cell Kit is designed for automated processing of both small numbers of samples individually, as well as large numbers of samples using a liquid handling robot or a multi-channel pipette.

For processing up to 24 individual samples at a time the MagnaRack™ two-piece magnetic separation tube rack is required. This rack consists of a magnetic base station and a removable tube rack, which can hold up to 24 microcentrifuge tubes and can be used with most ChargeSwitch™ products.

For high-throughput applications utilizing 96 well blocks, the 96-Well Magnetic Separator is required. This rack can hold and separate up to 96 magnetic bead samples in a deep well plate when placed on top of the magnetic base station.
