Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2. This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca ...
Tetrasodium EDTA is the salt resulting from the neutralization of ethylenediaminetetraacetic acid with four equivalents of sodium hydroxide (or an equivalent sodium base). It is a white solid that is highly soluble in water. Commercial samples are often hydrated, e.g. Na 4 EDTA. 4H 2 O. The properties of solutions produced from the anhydrous ...
TAE buffer is commonly prepared as a 50× stock solution for laboratory use. A 50× stock solution can be prepared by dissolving 242 g Tris base in water, adding 57.1 ml glacial acetic acid, and 100 ml of 500 mM EDTA (pH 8.0) solution, and bringing the final volume up to 1 litre.
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 Mg 2+.
TBE or Tris/Borate/EDTA, is a buffer solution containing a mixture of Tris base, boric acid and EDTA. In molecular biology, TBE and TAE buffers are often used in procedures involving nucleic acids , the most common being electrophoresis .
Poison Profits. A HuffPost / WNYC investigation into lead contamination in New York City
Federal Reserve Chair Jerome Powell said Wednesday that President Donald Trump's calls for lower interest rates won't lead the central bank to change its rate decisions. “People can be confident ...
The [Fe(EDTA)(H 2 O)] − anion has been crystallized with many cations, e.g., the trihydrate Na[Fe(EDTA)(H 2 O)]. 2H 2 O. [3] The salts as well as the solutions are yellow-brown. Provided the nutrient solution in which the [Fe(EDTA)(H 2 O)] − complex will be used has a pH of at least 5.5, all the uncomplexed iron, as a result of incomplete ...
