L. Moesby et al., A comparative study of Mono Mac 6 cells, isolated mononuclear cells and Limulus amoebocyte lysate assay in pyrogen testing, INT J PHARM, 191(2), 1999, pp. 141-149
Pyrogen induced secretion of interleukin 6 (IL-6) in Mono Mac 6 (MM6) cells
was measured. The ability of the MM6 cell culture to detect pyrogens was c
ompared to the Limulus amoebocyte lysate (LAL) test and isolated mononuclea
r cells (MNC). The detection limit of MM6 for lipopolysaccharide (LPS) and
Staphylococcus aureus was comparable to that of MNC. Aspergillus niger and
Candida albicans induced IL-6 in isolated MNC, but not in MM6. The detectio
n limit for Salmonella typhimurium? in the MM6 assay was comparable to that
of the LAL assay. As expected, S. aureus and C. albicans did not show any
LAL activity. A. niger and Influenza virus showed some activity in the LAL
test, but could not be detected by MM6 cells. In conclusion, the MM6 assay
is a good supplement to the current pyrogen assays for detection of LPS, S.
aureus and S. typhimurium?, but the MM6 assay could not detect A. niger, C
. albicans and Influenza virus. (C) 1999 Elsevier Science B.V. All rights r
