Test Kit for the Accurate Detection of Lysozyme

Despite their nutritional value, eggs represent a significant health issue for allergic individuals. Proteins from egg yolk have only minor allergenicity, but many proteins from the egg white are known to be allergenic.

In addition to ovalbumin, lysozyme represents the major allergenic protein found in egg white.

Lysozyme is frequently used as a preservative by the food industry. It is often deliberately added to dairy products or used as fining agent for wine. For allergic persons the consumption of lysozyme represents a critical problem. As very low levels of the allergen are enough to trigger allergic reactions, failing to label lysozyme additives in food can prove hazardous for allergic people.

Mandatory labeling of egg residues in food

To protect consumers from the potentially fatal consequences of egg consumption, allergen labeling is required by law in many countries. Egg is regulated for example by the EU Opens external link in new windowRegulation (EU) No 1169/201 and the U.S. Opens external link in new windowFDA – FALCPA 2004.

Fast and highly sensitive lysozyme analysis

The Romer Labs test kit portfolio covers a highly sensitive ELISA method for the quantitative analysis of lysozyme in environmental samples, rinse waters and finished food products.




The AgraQuant® Lysozyme 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.
