solubilize DNA
TE buffer is used to store and stabilize DNA and RNA samples with EDTA to chelate divalent cations that can degrade nucleic acids. TAE buffer is used for agarose gel electrophoresis of DNA with Tris-Acetate-EDTA to provide proper pH and conductivity for DNA migration. TAE buffer is preferred for electrophoresis due to its lower buffering capacity than TE buffer.
Tris(hydroxymethyl)aminomethane (Tris) is a common buffer used in biochemistry, while Tris HCl is Tris buffer combined with hydrochloric acid to adjust the pH. Tris buffer is neutral (pH 7-9), while Tris HCl is acidic with a pH around 4.5-8.6.
Phenol is not miscible in tris buffer because phenol is a hydrophobic compound, while tris buffer is an aqueous solution. Hydrophobic compounds like phenol tend to separate from water-based solutions like tris buffer due to differences in polarity and interactions with water molecules. This results in the immiscibility of phenol in tris buffer.
The conductivity of a 1 millimole tris buffer solution will depend on the concentration of the buffer solution and the specific conductance of tris buffer at that concentration. Conductivity is a measure of the ability of a solution to conduct an electric current, and is influenced by factors such as ion concentration and temperature.
TBE (Tris-borate-EDTA) buffer is used for nucleic acid electrophoresis and provides better resolution of larger DNA fragments, while TAE (Tris-acetate-EDTA) buffer is commonly used for agarose gel electrophoresis of DNA. The primary difference between the two buffers is the anion used (borate vs. acetate), which can affect the mobility of DNA fragments during electrophoresis.
Chelating agent
The main difference is in composition. In TE common Tris buffer is bring down to pH 8 with HCl and EDTA is involved but in TAE instead of Tris HCl in TE Tris-acetate buffer is used.

DNA gels is a term that usually refers to agarose gels, made with TAE (Tris, Acetate, EDTA) or TBE (Tris, Borate, EDTA) buffer. They are the simplest to make and don't contain toxic compounds (unless EtBr is added to the gel).
It is a buffer used in biology. "te" is derived from its components: t from tris, a common pH buffer, and e from the EDTA, a molecule. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
Buffer ATE is a common buffer solution used in biological and biochemical laboratories. It typically consists of acetic acid, tris(hydroxymethyl)aminomethane (Tris), and EDTA (ethylenediaminetetraacetic acid). Buffer ATE is used to maintain a stable pH and prevent metal ion interference in experiments such as nucleic acid extraction or enzymatic reactions.
Feldman buffer is composed of Tris base, sodium chloride, and EDTA (ethylenediaminetetraacetic acid) at specific concentrations to maintain a stable pH around 7.6 for biological applications.

Tris, commonly used as a buffering agent in Tris-EDTA (TE) buffer, helps to maintain the pH stability of the solution during DNA elution. Tris also provides a suitable ionic strength for DNA stability and helps to prevent degradation. It facilitates the solubilization of DNA during elution by providing a mild and stable environment.
TE buffer is used to store and stabilize DNA and RNA samples with EDTA to chelate divalent cations that can degrade nucleic acids. TAE buffer is used for agarose gel electrophoresis of DNA with Tris-Acetate-EDTA to provide proper pH and conductivity for DNA migration.
