Do you want to validate your cleaning processes?
Are you thinking of doing allergen control but you do not know how to approach it?
Do you have many products to analyse and need quick results?
Do you have doubts about heating processing affecting your testing?
Proteon Milk allows to quantify the content of milk in any kind of food sample in 30 or 90 minutes. Thus, you could 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 milk, based on the binding of β-lactoglobulin, 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-lactoglobulin in the sample or standard will be directly proportional to the intensity of colour in the final product.
