NEW: Ultra-pure EndoGrade® Ovalbumin with < 0.1 EU/mg

The glycoprotein ovalbumin is an extensively studied protein in animal models and also an established model allergen for airway hyper-responsiveness (AHR).

Commercially available ovalbumin is often contaminated with endotoxin which activates endothelial cells in in vitro assays and leads to artefacts of research results.

To meet the requirement of our customers we provide EndoGrade® Ovalbumin at superior quality.
More than 70 scientists using EndoGrade® Ovalbumin have published their results.

EndoGrade® Ovalbumin Customer Feedback

Immunology test with endotoxin-free EndoGrade Ovalbumin resulting in no IL-12 induction!

"We do not observe any IL-12 induction and proliferation of dendritic cells after we pulsed them over night with Hyglos' ovalbumin (completely contrary to other OVA preparations).
Cultivation of OVA-T-cell-receptor transgenic T-cells pulsed with DCs leads to T-cell proliferation, which shows the processing and presentation of the antigen. In short: Optimal for our assays."

~ Prof. Dr. Tilo Biedermann, University Tübingen
