To compare the relative efficacy of DMSO with its metabolites, DMS and DMSO2, on modulating inflammatory responses, the 3 compounds were analyzed in the whole blood assay as described above. The three compounds were dissolved in autologous plasma instead of PBS to increase the solubility of DMS in the whole blood assay. Also, to prevent the volatile DMS from affecting the evaluation of other treatments (DMSO and DMSO2), the 96 well plate was sealed with a plate sealer during the 7 h incubation period.
