Chelating agent
Tris buffers provide a stable pH environment for biochemical reactions, while EDTA chelates metal ions to prevent enzymatic degradation. When used together, the Tris-EDTA (TE) buffer is commonly used for nucleic acid storage and as a buffer in molecular biology applications.
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.
tris, EDTA (TE solution) and NaCl, TNE buffer is a buffer solution used in molecular biology, especially for DNA and RNA

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.
Tris-NaCl-EDTA (TNE) buffer is used in molecular biology to maintain the stability and integrity of DNA or RNA molecules by providing optimal conditions for storage or transport. It helps to preserve nucleic acids by preventing enzymatic degradation and maintaining the appropriate pH and ionic strength.
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.
