Its molecular structure carries an imidazole side chain, which makes it one of the most chemically versatile of the amino acids. In the TCI catalogue this product is listed under the code H0149 and is grouped within the conjugation chemistry and click chemistry product lines, reflecting its role as a reactive and coordinating building block in modern biochemical work.\u003c\/p\u003e\n\u003cp\u003eThe main attraction of this compound lies in its imidazole ring, which can shift protonation state around physiological pH and therefore acts both as a buffering group and as an acid-base catalyst at the active sites of many enzymes. Its ability to form strong coordination bonds with nickel and cobalt ions underpins the purification of histidine-tagged proteins by immobilised metal affinity chromatography, one of the most widely used methods in modern molecular biology. As a pure L-enantiomer, the material suits experiments that demand optical purity.\u003c\/p\u003e\n\u003cp\u003eIn Indonesian laboratories, L-Histidine is used as a component of culture media formulations, as a constituent of buffer systems, as a metal-chelating ligand, and as a selective attachment point in a range of biomolecule conjugation and protein engineering strategies. These roles place it in university biochemistry teaching laboratories, molecular biology research groups, biotechnology facilities, and analytical laboratories preparing reference solutions and working media for routine and developmental work.\u003c\/p\u003e\n\u003ch3\u003eLaboratory Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCell and microbial culture media preparation — supplied as a defined amino acid component so that media composition remains controlled and reproducible across repeated culture batches.\u003c\/li\u003e\n\u003cli\u003eBuffer system formulation — the imidazole side chain changes protonation state near physiological pH, allowing the compound to stabilise solution pH in biochemical work.\u003c\/li\u003e\n\u003cli\u003eMetal-chelating ligand chemistry — the side chain coordinates strongly with transition metal ions, making it useful wherever a defined amino acid chelator is required.\u003c\/li\u003e\n\u003cli\u003eImmobilised metal affinity chromatography studies — its strong nickel and cobalt coordination is the chemical basis of histidine-tagged protein purification, a standard molecular biology technique.\u003c\/li\u003e\n\u003cli\u003eBioconjugation and protein engineering — serves as a selective attachment point in conjugation and click chemistry strategies for building modified biomolecules and protein constructs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: TCI (catalogue code H0149)\u003c\/li\u003e\n\u003cli\u003eCAS number: 71-00-1\u003c\/li\u003e\n\u003cli\u003eCategory: Chemistry \u0026gt; Chemical Biology \u0026gt; Conjugation Chemistry \/ Click Chemistry\u003c\/li\u003e\n\u003cli\u003eChemical identity: L-Histidine, the pure L-enantiomer, suitable for work requiring optical purity\u003c\/li\u003e\n\u003cli\u003ePack sizes: available in the pack sizes listed in the TCI catalogue for this item\u003c\/li\u003e\n\u003cli\u003eStorage: store according to the conditions stated on the manufacturer's label and safety data sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHandling and Storage\u003c\/h3\u003e\n\u003cp\u003eKeep the container tightly closed in a cool, dry, well-ventilated area, away from moisture, direct sunlight, and incompatible materials, and follow the storage conditions given on the manufacturer's label and safety data sheet.
