Albert Claude/Known for
What did Claude invent?
In 1930 he developed the technique of cell fractionation, by which he discovered the agent of the Rous sarcoma, components of cell organelles such as mitochondrion, chloroplast, endoplasmic reticulum, Golgi apparatus, ribosome and lysosome. He was the first to employ the electron microscope in the field of biology.
What 3 scientists won the Nobel Prize in Physiology or Medicine in 1974?
The Nobel Prize in Physiology or Medicine 1974 was awarded jointly to Albert Claude, Christian de Duve and George E. Palade “for their discoveries concerning the structural and functional organization of the cell.”

Who discovered the endoplasmic reticulum?
ER discovered by Emilio Veratti in the year of 1902 as Sarcoplasmic Reticulum in muscle fibers which is similar to ER in other cells (Veratti, 1961). Fifty years later, this new organelle was first visualized through electron microscopy (EM) by Keith Porter and termed it as “endoplasmic reticulum” (Porter, 1953).
What is cell fractionation biology?
Cell fractionation is the process used to separate cellular components while preserving individual functions of each component. This is a method that was originally used to demonstrate the cellular location of various biochemical processes.
Who discovered ER and ribosomes?
George E. Palade
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane.
Who discovered Golgi complex?
Camillo Golgi
The existence of the cell organelle which is now known as Golgi apparatus or Golgi complex, or simply as ‘the Golgi”, was first reported by Camillo Golgi in 1898, when he described in nerve cells an ‘internal reticular apparatus’ impregnated by a variant of his chromoargentic staining.
What is cell centrifugation?
Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. Centrifugation is used to collect cells, to precipitate DNA, to purify virus particles, and to distinguish subtle differences in the conformation of molecules.
How is centrifugation done?
Centrifugation is a technique used for the separation of particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. The particles are suspended in a liquid medium and placed in a centrifuge tube. The tube is then placed in a rotor and spun at a define speed.
Who was Albert Claude and what did he do?
Albert Claude. Albert Claude, (born August 24, 1898, Longlier, Belgium—died May 22, 1983, Brussels), Belgian-American cytologist who developed the principal methods of separating and analyzing components of the living cell. For this work, on which modern cell biology is partly based, Claude, his student George Palade,…
When did Albert Claude win the Nobel Prize?
For this work, on which modern cell biology is partly based, Claude, his student George Palade, and Christian de Duve shared the Nobel Prize for Physiology or Medicine in 1974.
When did Albert Claude use the electron microscope?
Claude turned in 1942 to the electron microscope —an instrument that had not been used in biological research—looking first at separated components, then at whole cells.
Where was Albert Claude Nobel born and raised?
I was born in Belgium, in 1899. Longlier, my birthplace, is located in a high point of the Belgian Ardennes, atop the rising spur of an eroded remnant of the foot of the Alps, next to a deep valley. In the Middle Ages, it had been a fortified place, of the Francs and Carolegian dynasties.
