Endotoxin Removal and Testing Services

Endotoxin Removal from biological solutions is critical for many in vivo and cell-based applications, as it interferes with biological response. Endotoxins are liposaccharides that are found in the outer cell wall of Gramm-negative bacteria. Bacteria release endotoxins at the time of lysis. The toxic effect of endotoxins is triggered by its interaction with specific receptors on the immune cells resulting in the release of high concentrations of cytokines and other molecules of immunological significance. Since adventitious endotoxin is present in air, water, labware and it cannot be removed by simple sterilization, it is almost impossible to generate endotoxin-free solutions without a removal procedure. Each Endotoxin Removal project requires a protocol development step that takes into consideration biophysical properties of a target molecule, final sample application and desired formulation. For years we had successfully developed endotoxin removal protocols to meet strict endotoxin presence requirements. We are confident that we can make your Endotoxin Removal project a success.
