TE buffer. TE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. TE is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
Technetium (/tÉkËniËÊiÉm/) is a chemical element with symbol Tc and atomic number 43. It is the element with the lowest atomic number in the periodic table that has no stable isotopes: every form of it is radioactive.Nearly all technetium is produced synthetically, and only minute amounts are found in nature.echnetium-99 (99 Tc) is a major product of the fission of uranium-235 (235 U), making it the most common and most readily available isotope of technetium. One gram of technetium-99 produces 6.2Ã10 8 disintegrations a second (that is, 0.62 G Bq /g).
