Required materials and instruments

About thermal

shakers

A thermal shaker was used in the validation studies described in Chapter 4 and is

recommended for DNA extraction using the PrepFiler™ Forensic DNA Extraction

Kit.

You can use a heat block (following the heat block instructions provided in the

protocols) instead of a thermal shaker, however the kit performance has not been

extensively tested under these conditions, and DNA yield may be lower than would

be obtained using a thermal shaker.

Each lab should perform studies to validate the performance of the PrepFiler kit

when using methodologies other than a thermal shaker.
