The following solvents should not be used with Luminex microspheres as they will affect the classification dyes in the microspheres: Aromatic Hydrocarbons (Benzene, Toluene, Xylene, Ethylbenzene), Chlorinated aliphatic Hydrocarbons (Methylene chloride, Chloroform, Carbon tetrachloride), and Others (Pyridine, Dioxane, Dimethylformamide, Methyl ethyl ketone, Cyclohexanone, Tetrahydrofuran, N-butyl phthalate, Methyl phthalate, Ethyl phthalate, Tetrahydrofurfuryl alcohol, Ethyl acetate, Butyl acetate, 1-nitro-propane, Carbon disulfide, Tributyl phosphate, Cyclohexane, Methylcyclohexane, Ethylcyclohexane, Acetone, DMSO).
High salt concentrations will also affect the classification of the microspheres on the Luminex 200 and FLEX 3D; as the salt concentration of the buffer increases, the microspheres will tend to spread out the bead map. High salt buffers (6X SSC, >0.2M NaCL) should be diluted or exchanged prior to analysis as they can interfere with microsphere classification.
