Ovalbumin is an extensively used allergen model in immunology and allergology studies.
Commercially available ovalbumin is often contaminated with endotoxin, which leads to artefacts and inaccurate results. Endotoxin-free EndoGrade® Ovalbumin is of superior quality with a guaranteed endotoxin level (LPS) below 0.1 EU/mg.
EndoGrade® Ovalbumin is manufactured in Germany by LIONEX GmbH.
