To exclude pyrogenic substances in sterile formulations, the determination of the absence of endotoxins is mandatory. This applies to both sterile pharmaceuticals as well as sterile medical devices. Labor LS offers a comprehensive range of biological purity tests in this field. All common LAL methods (A, C, D) are established for the detection of endotoxins of Gram-negative bacteria (LPS, lipopolysaccharides). The MAT (monocyte activation test) and the rFC assay (recombinant factor C) round off the test portfolio.
