FIG. 1.

Absorbance (A₂₅₄) profiles for linear sucrose gradient fractionation of 1, 4, and 8 dpp mouse testis lysates. The monosome (80S) is the highest resolved peak, and each peak to the right represents the addition of one ribosome to mRNAs (polysomes). Immunoblots below each profile were performed using antibodies against DDX6 and RPS6, with total protein isolated from the corresponding fraction noted above each lane (1–13).
