Milk ELISA kit is designed for measuring quantitative amounts of bovine milk protein present in food (for example chocolate, bread crumbs, cookies, soy products, sausage, orange juice and wine). This assay has a minimum analytical sensitivity limit of 0.05 ppm.
Milk is usually processed into dairy products for example butter, cheese, yogurt, cream and ice-cream. It can also be found in many other found such as bread, breakfast cereals, processed meats, ready meals, soups, pizza, puddings and custards, sweets and cakes to juts name a few. A milk allergy, is very much like most of the other food allergies, it can occur during early infancy and cows’ milk protein allergy is regarded as the most frequent, however, many children tend to grow out of this allergy after the age of 5. Even low amounts of bovine milk can lead to allergic reactions and it may cause an anaphylactic shock in severe cases. An individual that it allergic to milk should therefore avoid milk or even the presence of hidden milk proteins present in foods such as convenience food, cookies, sausage and beverages. Approx. 80 % of bovine milk proteins are caseins and also beta-Lactoglobulin, represents a major allergen of whey (this represents an additional 10% of the total protein). In order to measure bovine milk in foodstuffs, a highly sensitive detection procedure is essential. The following milk ELISA kit offers a very sensitive method for analysing milk based on NIST 1549 reference material, this protocol is validated to quantify casein and ß-lactoglobulin residues present in foods such as sausage, soy products, bread crumbs, cookies, chocolate, wine and orange juice.
The minimum detection sensitivity level of bovine milk using current milk ELISA kit was 0.05 ppm. The standard range for this assay is 0.4 – 10.0 ppm.
