Beta-Lactoglobulin Test Kits for Lab and On-Site Detection
Beta-Lactoglobulin (ß-lactoglobulin, BLG) 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 beta-lactoglobulin. It is often the main ingredient in whey-based protein powders.
Whey proteins can be dangerous food allergens. Bovine milk is one of the most important allergenic food ingredients, especially for children. Consequently, the labeling of beta-lactoglobulin or milk is mandatory in many countries. Although there are no legal threshold limits for whey proteins, it is highly recommended that food manufacturers test for very low concentrations to protect allergic individuals and avoid allergen-related recalls.
Mandatory labeling of milk residues in food
To protect consumers from the potentially fatal consequences of milk consumption, allergen labeling is required by law in many countries. Milk is regulated for example by 
Regulation (EU) No 1169/201 or U.S. FDA – FALCPA (2004).
Fast and highly sensitive beta-lactoglobulin analysis
The Romer Labs beta-lactoglobulin test kit portfolio covers ELISA tests and LFDs for the quantitative and qualitative analysis of beta-lactoglobulin in environmental samples, rinse waters and finished food products.
AgraStrip®
Lateral Flow Devices
The AgraStrip® Beta-Lactoglobulin test kit is a ready-to-use lateral flow device (LFD) for on-site testing. This immunological test allows a rapid analysis of a wide range of food samples within only 11 minutes (including extraction).
AgraStrip® LFDs represent a fast and simple qualitative strip test method in which specific antibodies labeled with colloidal gold are used for visual color development at a test and control zone.
The test kit comes complete with strips, antibody coated incubation vials, extraction tubes, an extraction buffer, surface swabs and additional accessories.

AgraQuant®
ELISA Tests
The AgraQuant® Beta-Lactoglobulin test kit is an accurate and reliable enzyme-linked immunosorbent assay (ELISA) in a quantitative format. Results are measured with a specific ELISA reader, such as the StatFax® or the BioTek® reader.
This ELISA test kit is the ideal solution for a parallel measurement of multiple samples with assay times of as low as 60 minutes for up to 38 samples.
AgraQuant® allergen test kits are sandwich ELISAs in a ready-to-use format to reduce handling errors and come with a set of 5 standards, an antibody coated plate, an extraction solution, a wash buffer, a conjugate, a substrate and a stop solution.
