Fig. 2 Two-dimensional PAGE analysis of sperm-associated proteins on condensed chromatin and following chromatin decondensation in egg extract and purified nucleoplasmin. Sperm nuclei were incubated in either (A) buffer, (B) Xenopus egg HSS, or (C) purified egg nucleoplasmin for 10 min. The nuclei were then pelleted, washed, and the chromatin-associated proteins were extracted with acid and analyzed in the first dimension by Triton-acid-urea (TAU)-PACE (left to right) and in the second dimension by SDS-PAGE (top to bottom). The positions of the core histones are indicated as H2A, H2B. H3. and H4 and the sperm-specific basic proteins as X and Y. The arrowheads and arrow indicate the positions of the cleavage-stage linker histone. B4, and Xenopus HMG-2, respectively (Dimitrov et at., 1994).
