Preparations
For common usage it is compounded with carbohydrazide (CH) and prepared as a Lithium salt. The CH group allows it to be covalently linked to surrounding biomolecules during aldehyde fixation.
Other cations such as ammonium or potassium can be used when lithium is undesirable, but the resulting salts are less soluble in water.
Lucifer yellow can also be compounded as a vinyl sulfone, with ethylenediamine, or with cadaverine.

Famous quotes containing the word preparations:
“At the ramparts on the cliff near the old Parliament House I counted twenty-four thirty-two-pounders in a row, pointed over the harbor, with their balls piled pyramid-wise between them,—there are said to be in all about one hundred and eighty guns mounted at Quebec,—all which were faithfully kept dusted by officials, in accordance with the motto, “In time of peace prepare for war”; but I saw no preparations for peace: she was plainly an uninvited guest.”
—Henry David Thoreau (1817–1862)
“Whatever may be the reason, whether it was that Hitler thought he might get away with what he had got without fighting for it, or whether it was that after all the preparations were not sufficiently complete—however, one thing is certain: he missed the bus.”
—Neville Chamberlain (1869–1940)
“The most evident difference between man and animals is this: the beast, in as much as it is largely motivated by the senses and with little perception of the past or future, lives only for the present. But man, because he is endowed with reason by which he is able to perceive relationships, sees the causes of things, understands the reciprocal nature of cause and effect, makes analogies, easily surveys the whole course of his life, and makes the necessary preparations for its conduct.”
—Marcus Tullius Cicero (106–43 B.C.)
