DNA is the basis for species identity and is the only method capable of truly authenticating ingredients of biological origin, including plants, animals, fungi and bacteria. In fact, DNA is the most commonly used method by university scientists around the world for identifying species. And now, AuthenTechnologies® is the first contract laboratory in the world to bring this valuable service to the public. Click here for a list of AuthenTechnologies® standard DNA identity testing services.
DNA is the most sensitive, specific, and accurate method of species identification on the market, and the scientists at AuthenTechnologies are the world-leaders in species identification using DNA. In fact, over 25% of our routine samples are found to be adulterated, most by closely related species not detectable by any other method. Our scientists have developed cutting-edge genetic methods capable of identifying a single organism to a complex blend of 100 or more.
Because conclusive and reliable ingredient authentication is paramount for developing safe and high-quality natural products, using DNA ingredient authentication services at AuthenTechnologies® can dramatically improve your products- and your business. Don’t just take our word for it, click here to see what our clients have to say about it. Or read a true story from our lab below.
As part of an internal research project at AuthenTechnologies®, we tested a number of finished products dietary supplements off the shelf, including a $50 bottle of goldenseal from a major manufacturer. Using our Confirm IDNA™ test we identified that instead of it being the highly valuable herb goldenseal, it in fact was a common roadside weed plantain. This result was very unexpected for the manufacture of the product because it was yellow in color as goldenseal is, and had passed TLC testing. Further investigation found that the yellow color was in fact dye and the culprits had used an additive to trick the TLC test.
The manufacturer was very concerned so they decided to investigate additional samples from the same supplier. Further testing revealed that out of ten additional samples from the same supplier, only two were true goldenseal. However, the adulterated products were not the common goldenseal adulterants, but instead contained pure nettle root, plantain root, and even passionflower root- all dyed yellow and spiked with a chemical to trick TLC testing. This illustrates how you may be able to trick morphological analysis or TLC- but you can’t trick DNA.
The picture above illustrates the “goldenseal” samples mixed in water; the authentic goldenseal reference on the far right is brown in color, while those spiked with yellow die have produced bright yellow water.
