AgraStrip® β-Lactoglobulin Kit

User friendly kit for the analysis of β-Lactoglobulin residue in foods, rinse waters and environmental surfaces.

ß-Lactoglobulin is the major whey protein in ruminant milk and is also present in the milk of other animals. About 20% of bovine milk proteins are whey proteins, with the main component being ß-Lactoglobulin.

Very low amounts of bovine milk can cause allergic reactions including anaphylactic shock, and sufferers must therefore follow a strict diet avoiding the ingestion of milk.  As milk is used widely as a food additive, it is often hidden in products such as sausages, deli meats, and ready to eat meals. It is therefore important that food manufacturers declare the inclusion of milk on product labels.

AgraStrip® β-Lactoglobulin test kits are a ready to sue lateral flow device (LFD) for on-site testing. These immunological tests allow a rapid analysis of a wide range of food samples within 11 minutes (including extraction). AgraStrip® LFD's provide a fast and simple qualitative strip test method in which specific antibodies labelled with colloidal gold are used for visual colour development at a test and control zone.

The test kit is supplied complete with 10 strips, antibody coated incubation vials, extraction tubes, an extraction buffer, surface swabs and additional accessories.
