THP-G8 cells are utilized for the in vitro skin sensitisation test (IL-8 Luc Assay), which is approved as an internationally recognized testing protocol by the Organization for Economic Co-operation and Development (OECD).
The THP-G8 cells are derived from human acute monocytic leukemia cell line (THP-1 cells) stably introducing luciferase genes, in which orange-emitting luciferase (Stable Luciferase Orange, SLO) is expressed under the control of interleukin-8 (IL-8) promoter, and red-emitting luciferase (Stable Luciferase Red, SLR) is expressed under the control of GAPDH promoter, used as an internal control reporter.
To evaluate skin sensitisation, transcriptional activation of interleukin-8 (IL-8) promoter by test chemicals, seen in human dendritic cells in skin, is simply measured by luciferase reporter assay.
* THP-G8 cells were established by Department of Dermatology, Tohoku University School of Medicine (Takahashi T. et al. Toxicol. Sci., 124, 359-369, 2011).

2H4 cells are utilized for the in vitro immunotoxicity test (IL-2 Luc Assay), which is approved as an internationally recognized testing protocol by the Organization for Economic Co-operation and Development (OECD).
2H4 cells are derived from human acute T lymphoblastic cell line (Jurkat cells) stably introducing luciferase genes, in which green-emitting luciferase (Stable Luciferase Green, SLG) is expressed under the control of interleukin-2 (IL-2) promoter, orange-emitting luciferase (Stable Luciferase Orange, SLO) is expressed under the control of interferon (IFN)- γ promoter, and red-emitting luciferase (Stable Luciferase Red, SLR) is expressed under the control of GAPDH promoter, used as an internal control reporter.
To evaluate immunotoxicity, transcriptional change of IL-2 promoter of human T cells by immunotoxic chemicals is simply measured by luciferase reporter assay.
*2H4 cells were established by Tsuruga Institute of Biotechnology, TOYOBO CO., LTD., and Department of Dermatology, Tohoku University School of Medicine (Saito R. et al.(2011) Toxicol. Appl. Pharmacol., 254, 245-255).
