Level of endotoxin

The level of endotoxin is caused by the medium which is used for the production/ cultivation of the mites. In our production process we do not add any proteins. The only compound we use in our products which is not strictly from mites is the medium where the mites feed on. This medium contains an absolute low number of non-mite proteins. We try to cultivate the mites with the lowest amount of bacteria and moulds possible. All of our products will be delivered with a certificate of analysis and the level of endotoxin.

For the use in an allergic asthma animal model a certain level of endotoxin is needed. But for the use in cell cultures a endotoxin free (or very low) extract is needed.
