Pyrogens as fever-inducing agents can be a major health hazard in parenterally applied drugs.Currently, rabbit pyrogen test and the limulus amoebocyte lysate test (LAL) as the pharmacopoeia tests were used to control these contaminants.Whereas, rabbit pyrogen is the troublesome, costly and controversial use of laboratory animals, and LAL does not detect pyrogens other than lipopolysaccharide (LPS), which limits the use of these typical tests.In our study, we found that human promyelocytic leukemia cell line (SJ-1) stimulated by LPS, zymosan and lipoteichoic acid (LTA) can secrete interleukin-6(IL-6), which could be an indicator of pyrogen contamination.Furthermore, the linear between the concentration of pyrogen and IL-6 amount was very good (R2>0.97).According to our data, we established a novel cell-based pyrogen test, which has a lower limit of detection and could be a good supplement to the current pyrogen assays.
