Fig. 1. Fluorogram of L-[³⁵S]methionine-labelled proteins from a wheat germ cell-free translation assay of Xenopus ß-globin mRNA (G), lobster eyestalk poly(A)⁺ RNA (L) and water control (C). 5 µl of translation product was loaded in lanes 1, 2 and 4, and 10 µl in lanes 3, 5 and 6, on a 12 % polyacrylamide-SDS gel. Protein molecular mass standards (kDa) are indicated on the left. The dried gel was exposed for fluorography for 3 days at -80 °C, with intensifying screens.
