Insulin-degrading enzyme, also known as IDE, is an enzyme. [ 4 ] Known alternatively as insulysin or insulin protease , IDE is a large zinc-binding protease of the M16 metalloprotease family known to cleave multiple short polypeptides that vary considerably in sequence.
Lanthanide metals react exothermically with hydrogen to form LnH 2, dihydrides. [1] With the exception of Eu and Yb, which resemble the Ba and Ca hydrides (non-conducting, transparent salt-like compounds),they form black pyrophoric, conducting compounds [6] where the metal sub-lattice is face centred cubic and the H atoms occupy tetrahedral sites.

The lanthanide trichlorides can generally be prepared by dissolving the oxide or carbonate with hydrochloric acid. They are produced commercially by carbothermic reaction of the oxide. To produce the anhydrous forms of these trichlorides, the ammonium chloride route is taken. The anhydrous lanthanide trichlorides have high melting points and ...
The lanthanides obey the Oddo–Harkins rule – odd-numbered elements are less abundant than their even-numbered neighbors. Three of the lanthanide elements have radioactive isotopes with long half-lives (138 La, 147 Sm and 176 Lu) that can be used to date minerals and rocks from Earth, the Moon and meteorites. [88]

The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
Targets are selected to answer a specific research question and are labeled with lanthanide metal tagged antibodies. Labeled cells are nebulized and mixed with heated argon gas to dry the cell containing particles. The sample-gas mixture is focused and ignited with an argon plasma torch. This breaks the cells into their individual atoms and ...
