Description
Poly-L-lysine hydrobromide is a cationic polyamino acid salt offered at a minimum purity of 95 % with a molecular weight range of 1000–5000 (CAS 25988-63-0). The polymer is described by the empirical formula (C₆H₁₂N₂O₂)ₙ(HBr)ₓ, corresponding to the hydrobromide form of polymerised L-lysine. This biochemical is available from manufacturer Carl ROTH within a research-oriented chemicals portfolio. Typical uses include preparation of coated slides and dishes, adhesion assays, and related cell-biology or biochemistry protocols that rely on electrostatic interaction between the polylysine backbone and negatively charged surfaces or membranes. The stated molecular-weight window helps laboratories prepare working solutions and coating baths with consistent handling characteristics. With clear CAS identification, purity specification, and a compact pack size, poly-L-lysine hydrobromide suits method development, pilot coating trials, and routine experimental setups that require a defined polylysine hydrobromide reagent in small quantities.

Questions about Poly-L-lysine hydrobromide, min. 95 %, M.W, 1000-5000, 25 mg
What is this article?
Poly-L-lysine hydrobromide, min. 95 %, M.W, 1000-5000, 25 mg 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 Life Science & Microbiology.
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.
