Fractionation of ODC protein and of cytoskeletal
components. 35S-labeled NHEK fractions were
immunoprecipitated with ODC antibody or probed for actin, tubulin, or
keratin by Western blotting, using the fractionation scheme detailed in
Figure 8. ODC protein was present in all fractions, as was actin.
Tubulin was found only in the S0 fractions, with keratin
only in the P1 fractions.
