Can Aptamers Give Us Better, Faster Gluten Detection?

Celiac.com 07/04/2016 - The fast rising number of people diagnosed with celiac disease creates challenges to both the food industry and public officials to guarantee safe food.

A great deal of effort is going into determining minimal celiac disease-eliciting doses of gluten and to refine and improve gluten-free labeling.

A team of researchers recently set out to assess the harnessing of aptamers to overcome challenges in gluten detection. The research team included Rebeca Miranda-Castro, Noemí de-los-Santos-Álvarez, Arturo J. Miranda-Ordieres and María Jesús Lobo-Castañón of the Departamento de Química-Física y Analítica, Universidad de Oviedo in Oviedo, Spain.

Their efforts rely largely on the ability to detect gluten protein in food samples at the lowest levels possible. Current analytical devices use antibodies to determine gluten protein levels. These devices have limited sensitivity, and also have some issues with the accuracy and reliability. Aptamers provide an ideal alternative for designing biosensors that can quickly and reliably measure gluten in foods.

The team's article highlights the challenges in gluten detection, the current status of the use of aptamers for solving this problem, and what remains to be done to move these systems into commercial applications. They conclude: "The new receptors present high affinity and binding selectivity. In addition, they can be easily labeled with different reporter molecules at a relatively low production cost. These attributes make aptamers ideal reagents for the development of chemical sensors and analytical assays...Although still in its infancy, this sensitive technology will undoubtedly continue to advance."

There are plenty of people that have gone gluten free without the official diagnosis because a gluten challenge would make them too sick. I think you are the only one that will know if it's right for you. There are some benefits to getting diagnosed as either celiac or NCGS. 1. If you are...

Oh, I would hate to have you test negative because your gluten challenge was not long enough. http://www.cureceliacdisease.org/faq/what-is-a-gluten-challenge/ https://www.beyondceliac.org/celiac-disease/Testing-and-Diagnosis/The-Gluten-Challenge/1510/ https://www.ncbi.nlm.nih.gov/p...

thank you guys. I'm hoping the Gi will call back tomorrow. I'm getting the kitchen totally gluten free, except for a few things my sister who is a bit disabled is going to have. But no bread, flour, pasta and most other things will not have gluten. And my daughter doesn't go to school, she d...

Unprocessed food is great, but a life without chocolate no way! Am sure you will find a suitable brand. I don't eat Lindt, think they may use barley, others may know more. The Moser Roth are Aldi own brand. Looks like Aldi aren't in CR so not an alternative for you sorry. Maybe chec...

Ok guys, I'm not an expert. Maybe it was really just cc as Matt said. Or my body is just too sensitive now and this thing is too artificial/chemical. I feel that real unprocessed food is better for me now. It won't be a problem to find another brand. The Moser Roth doesn't sound familiar t...
