Description
E-64 is a cysteine protease inhibitor supplied at min. 99 % purity for biochemistry. It carries CAS number 66701-25-5, the empirical formula C₁₅H₂₇N₅O₅ · 0,5 H₂O, and a molar mass of 357,41 g/mol. This reagent is used in life-science laboratories to suppress cysteine protease activity during cell lysis, protein isolation, and related biochemical procedures. E-64 from manufacturer Carl ROTH provides a high-purity option for investigators who need a clearly characterised inhibitor with documented molecular data. The minimum 99 % specification supports reproducible inhibition conditions across replicate assays and method development. Its compact presentation helps laboratories manage specialised reagents efficiently while maintaining adequate material for multiple preparations. Intended for professional biochemistry use, E-64 integrates readily into inhibitor cocktails or single-agent protease-control strategies under standard laboratory handling practices.

Questions about E-64, min. 99 %, for biochemistry, 5 mg, plastic
What is this article?
E-64, min. 99 %, for biochemistry, 5 mg, plastic 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.
