Genscript ToxinSensorTM Chromogenic LAL Endotoxin Assay Kit is designed to be a quantitative In Vitro end-point endotoxin test for human and animal parenteral drugs, biological products, and medical devices. This method utilizes a modified Limulus Amebocyte Lysate and a synthetic color producing substrate to detect endotoxin chromogenically in a broad range of 0.005 - 1 EU/ml. In addition, any sample with color (e.g. cell bacterial culture medium, serum or blood etc.) can not be assayed by this kit.
