In addition, our works also indicate that MC-ICPMS technique shows a good potential on Re-Os isotopic measurement. 2. A new method for the determination of low Re-Os abundances and ~(187)Os/~(188)Os in a natural rock sample by MC-ICP-MS has been established in our laboratory. Rock samples were digested in inverse aqua regia in sealed Carius tube for 24 hours at 230°C, then Os was separated from the matrix by CCl_4 solvent extraction, and further purification by microdistillation.

METHODS: Rat bilateral olfactory bulbs and olfactory mucosa at 1/3 nasal septum were obtained, sliced, digested in trypsin, and made into monoplast suspension. At 1×109/L, cells were incubated in uncoated 25 cm2 culture flask. At 18-20 hours, cell suspension was moved into another uncoated 25 cm2 culture flask (the first differential adhesion). At 24 hours, cell suspension was moved into a poly-D-lysine-coated 25 cm2 culture flask or poly-D-lysine-coated 6-well culture plate (the second differential adhesion). At 48 hours, parenchyma cells were removed after a half of medium was changed.

METHODS: Olfactory bulb was sterilely collected from rats, digested, and centrifuged. After removal of the supernatant, the olfactory bulb was resuspended with DMEM/F-12 medium containing 0.2 volume fraction of fetal bovine serum. The diluted monoplast suspension was equally assigned into 3 samples, and separately used for simple modified differential adherence, simple serum-free conditioned medium, and modified differential adherence + serum-free conditioned medium.
