SERATEC® Amylase Paper Test

The SERATEC® Amylase Paper Test is an essential diagnostic tool for forensic laboratories seeking to differentiate between biological fluids and mere “touch” DNA. While DNA profiling can identify who left a biological signature, the SERATEC® Amylase Paper provides the critical context of how it was deposited. By accurately localising and confirming the presence of saliva, investigators can establish a clear link between a DNA profile and a specific physiological source.

This kit is engineered for high-performance screening, capable of detecting saliva even in highly diluted samples. With a sensitivity threshold as low as 1/1000 (saliva to buffer ratio), it ensures that even trace amounts of amylase—often invisible to the naked eye or under standard forensic light sources—are identified.

The inclusion of a specialised Iodine Solution facilitates a clear, visual reaction on the paper, mapping the exact geometry of the stain. This “press test” method is non-destructive to the underlying DNA, meaning that once the saliva is located, the specific area can be sampled for downstream STR analysis with confidence. This distinction is vital in courtrooms, as it helps prove that the DNA originated from an intimate biological fluid rather than incidental skin cell transfer.

Designed for simplicity and reliability, the SERATEC® Amylase Paper is easy to use for both experienced serologists and field technicians. Each sheet is manufactured to strict quality standards, ensuring consistency across different batches and reducing the risk of false negatives.
