OxProtect GmbH

OxProtect is a company (SME) that develops new test procedures and active substances in the field of hemostasis and inflammation, founded in 2014. The research focus of the OxProtect GmbH is to examine blood cells on the activation status or the functional capacity (platelets, monocytes, granulocytes, t-cells), but also endothelial cells and joint cells. The function of the cells as well as the changes or activity can be analysed by flow cytometry, aggregation assays, adhesion assays or ELISA assays.


Not only human cell function testing but also animal cell function testing is established in the OxProtect GmbH, for example for mouse, rat, rabbit, sheep, or many other animal species cells. On these cells OxProtect can examine for example antibody binding, antigen binding, morphology, cell associate formation and cell fragmentation.


OxProtect moreover offers new developed analytical methods in the area of misfolded proteins, which among other things are built within and/or after diseases. These misfolded proteins play a pivotal role in blood coagulation and inflammation.


For protein qualification and quantification with special tools we use techniques like SDS-PAGE, 2D electrophoresis, and Western Blot analysis, for cell analysis approved and new developed immunocytochemistry assays.
