Friedrich Miescher worked with white blood cells obtained from pus collected from surgical bandages. He isolated and identified a new substance which he called nuclein, later known as DNA.
It is not ideal to isolate DNA from pus collected from bandages as it may contain contaminants from the wound environment. Using white blood cells obtained from a blood sample would provide a purer source of DNA for isolation techniques. This can be done by extracting white blood cells from the blood sample and isolating DNA from these cells using appropriate methods.
DNA was first isolated by the Swiss physician Friedrich Miescher who, in 1869, discovered a microscopic substance in the pus of discarded surgical bandages. As it resided in the nuclei of cells, he called it "nuclein"
Sulfur is typically isolated through a process called Frasch mining, where superheated water and air are pumped into underground sulfur deposits, causing the sulfur to melt and rise to the surface. The molten sulfur is then collected and cooled to solidify. Alternatively, sulfur can also be isolated as a byproduct of natural gas and oil refining processes.
The adjective for "isolated" is "lonely" or "secluded."
