Do you want to make internal validations occasionally?
Are you thinking of doing allergen control but you do not know how to approach it?
Do you need to know the quantity of soy to guarantee correct labelling?
Do you have many products to analyse and you need results quickly?
Do you have doubts about if heating treatment affects your testing?
Proteon Milk allows to quantify the content of soy in any kind of food sample in 90 minutes. Thus, you can comply with your quality requirements within the appropriate time. Concentration values will let you estimate the risks of your product against the VITAL criterion.
Proteon Milk is an ELISA sandwich for the detection of soy, based on the binding of β-conglicinin, present in the samples or standards, to a specific antibody immobilized onto the surface of the wells. This specific binding can be visualized later by applying an enzyme-antibody conjugate. The enzyme will react with a specific substrate and a colorimetric substrate will develop. The quantity of β-conglicinin in the sample or standard will be directly proportional to the intensity of colour in the final product.
