Control Material

We have an extensive archive of control material. We use this to determine, for all assays, a reference range and cut-off values for negative and positive quality control samples. (Reference compounds used for positive quality control are chlorpromazine, 8-methoxypsoralen, and porphyrin.)

Cell lines are maintained in antibiotic-free conditions and are regularly screened for mycoplasma. A range of cell lines is available, useful not only for photosafety and skin research, but also for the development of photoactivated therapeutics targeted to other tissues.
