It is used for the fast testing of: Saliva – Human salivary α-amylase-specific antibodies are conjugated with colloidal gold and incorporated beneath the sample window. An anti-α-amylase antibody is fixed at the test line. If human salivary amylase is present in the sample, it will form an antigen-antibody-colloidal gold complex upon ...
A presumptive test to detect saliva is the alpha-amylase test also known as the Phadebas Test. [4] This detection technique is based on the activity of the enzyme alpha-amylase which breaks down starches from food into smaller oligosaccharide molecules, starting digestion in the mouth. [ 11 ]
The Phadebas Forensic Press test is used as a presumptive test for saliva. [5] Phadebas may be used to find saliva as a DNA source, or to identify the origin of a stain. The test is performed by placing paper bound with the Phadebas substrate to a sample, and applying pressure. [5]
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.

A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...
Testing DNA is a technique which can detect specific genomes in a DNA strand to produce a unique and individualized pattern. DNA sequencing may be used along with DNA profiling methods for forensic identification and paternity testing , as it has evolved significantly over the past few decades to ultimately link a DNA print to what is under ...
Normally priced at $99, you can get an AncestryDNA kit for the lowest price we've ever seen ahead of Black Friday. For just $39, you can send in your DNA and learn a bevy of secrets, including ...
Oragene is the trade name for DNA Genotek's non-invasive DNA self-collection kit. Oragene allows the collection, stabilization and long-term storage of DNA from saliva at ambient temperature. Oragene first became available to the genetic research community in 2004. Oragene is available in a variety of formats for various markets.
