Description
Biotin-PEG6-NHS ester is an amine-reactive biotinylation reagent with a minimum purity of 95 %, CAS number 2055045-04-8, empirical formula C₂₉H₄₈N₄O₁₂S and molar mass 676,8 g/mol. The N-hydroxysuccinimide ester enables covalent coupling to primary amines on proteins, peptides and other biomolecules, while the PEG6 spacer improves solubility and reduces steric hindrance between the biotin moiety and the target. Laboratories use such biotin-PEG-NHS reagents to prepare probes for streptavidin-based capture, ELISA formats, surface functionalisation and imaging assays. The defined linker length and activated ester chemistry support controlled conjugation under typical aqueous or mixed-solvent conditions. This material from manufacturer Carl ROTH fits research and method-development settings that require reliable biotin introduction with a hydrophilic spacer. Clear molecular identity and documented molar mass facilitate stoichiometry calculations and reproducible labelling protocols.

Questions about Biotin-PEG6-NHS ester, min. 95 %, 50 mg
What is this article?
Biotin-PEG6-NHS ester, min. 95 %, 50 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Coenzymes, nucleotides & vitamins, inside Biochemicals & reagents, in Microbiology lab supplies.
Coenzymes, nucleotides and vitamins are the small molecules enzymes and cells consume: NAD, ATP, a vitamin cofactor. Purity, salt form and hydration are the specification, and many are unstable in solution or in the light. The lot is stored as the label says, often cold.
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.
