People Also Ask about

What is calf thymus DNA used for?

Deoxyribonucleic acid−cellulose double-stranded from calf thymus DNA is used to study the binding parameters and binding specificity of a variety of proteins, nucleotides, and chemical reagents including anti-cancer agents. It is frequently used in pull-down assays and chromatographic procedures.

At what temperature does calf thymus DNA melt?

For reconstituted polylysine-calf thymus DNA complexes, in addition to the melting of free DNA regions at about 50 degrees (T(m)) there is another melting at about 106 degrees (T(m)) of polylysine-bound regions. The melting band of the complex at T(m) is not symmetrical.

What is calf thymus extract?

Overview. The human thymus gland is responsible for the production of some important immune cells, such as T-cells. Thymus extract is produced from the thymus glands of cows. Some people use it as medicine. But the quality and potency of thymus extract products can vary greatly.

What does sulfur mustard do to the body?

Sulfur mustard is a human-made chemical warfare agent that causes blistering of the skin and mucous membranes on contact. This type of chemical warfare agent is called a vesicant or blistering agent. Sulfur mustard is known as "mustard gas," "mustard agent," or by the military designation "H" or "HD."

How big is the DNA in the calf thymus?

Calf Thymus DNA preparations have a fragment size range of 80–500 bp and are qualified for Northern, Southern, probe array, and dot blotting procedures.

What is the Meyer process of sulfur mustard?

The Germans produced sulfur mustard using the Meyer process, which involved treating ethylene with hypochlorous acid followed by sodium sulfide, yielding β,β'-dihydroxy-methyl sulfide. This in turn was heated with hydrochloric acid, which produced sulfur mustard.

Why thymus gland is always preferred gland for DNA extraction?

The thymus is a gland that is very large in immature mammals. It serves a function as a part of the immune system so there are many white blood cells with many large nuclei. Many thousands of thymus cells will be used for the extraction, so you will be combining the DNA from thousands of nuclei.

Does mustard gas affect your DNA?

Sulfur mustard has been shown to induce mutations in specific DNA regions (r-RNA-coding locus) (Fahmy & Fahmy, 1971; IARC, 1975). Fishermen who were exposed to mustard gas from leaking shells picked up during fishing showed an increased incidence of sister chromatid exchange in the lymphocytes (Wulf et al., 1985).
