FIGURE 4.
Glycerol gradient fractionation of Prp8p, Snu114p, and Aar2p. RG8T cell extract containing full-length Prp8Tp (A) and RG8T/2173p extract containing Prp8T/2173p (B) were fractionated in 10%–30% glycerol gradients. Alternate gradient fractions were analyzed by Western blotting with anti-Snu114p and anti-Aar2p antibodies. (*) Aar2p near the top of the gradient (lanes 25).
