Questions about Boc-L-cysteine, 5 g
What is this article?
Boc-L-cysteine, 5 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Microbiology lab supplies.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
