D (+) Biotin [Vitamin H], 5g, is a laboratory-grade reagent available for use in various biochemical and molecular biology applications. Biotin is a crucial water-soluble B-vitamin involved in energy metabolism, fatty acid synthesis, and the regulation of gene expression. It is also a cofactor for carboxylases, enzymes that are essential for the metabolism of carbohydrates, proteins, and fats. This high-quality reagent is used in protein biotinylation, cell culture media preparation, and other applications requiring precise biotin levels. Biotin is integral to many research studies in enzyme kinetics, metabolic pathways, and gene regulation, offering excellent stability and reproducibility for laboratory experiments.
