- Soon after, Palade made the momentous discovery of the ribosome, the protein-synthesizing organelle. He recognized that ribosomes exist free in the cytoplasm or attached to the ER membranes, often arranged in patterns that we now know to represent polysomes (sets of ribosomes translating a single RNA molecule).

The prize was granted for his innovations in electron microscopy and cell fractionation which together laid the foundations of modern molecular cell biology, [3] the most notable discovery being the ribosomes of the endoplasmic reticulum – which he first described in 1955. [4] [5] [6] [7] [8]
In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane. Along with other...
Abstract. George Emil Palade’s scientific contributions significantly advanced the field of modern cell biology. He pioneered a multidisciplinary approach, combining cell fractionation, biochemistry, and electron microscopy, which led to the identification of the ribosome as the site of protein synthesis and elucidated the eukaryotic ...

Jan 1, 2005 · Ribosomes, or particles of Palade, in rat pancreas. PALADE. But when Palade noted a particulate component of the cytoplasm, he confirmed its presence using two different fixatives, and described its particular abundance in embryonic, rapidly proliferating, and glandular cells (Palade, 1955).
Oct 31, 2008 · Palade's work in the 1950s established the ribosome as the seat of protein synthesis in the cytoplasm. In the 1950s and 1960s, he teamed with Philip Siekevitz and then with Lewis Greene, Colvin Redman, David Sabatini, and Yutaka Tashiro to demonstrate that the dense membranes isolated by Claude represented fragments of ER with bound ribosomes.
