Answer:A 5 g package of synthetic biotin powder is supplied.
Answer:The product meets USP testing specifications and has a published assay of 97.5–102.0%.
Answer:No. It is biotin itself, not an activated biotinylation derivative or a ready-to-use labeling kit.
Sigma-Aldrich Biotin is a synthetic vitamin B7 reagent supplied as a 5 g solid package and manufactured to meet USP testing specifications. Biotin acts as a cofactor in carboxylase-dependent metabolic reactions, making it useful in biochemical research and formulation work where a defined vitamin source is required. The product has an assay specification of 97.5–102.0% and a molecular weight of 244.31 g/mol. It is a research chemical rather than a ready-to-use biotinylation kit or streptavidin reagent. Prepare solutions at concentrations appropriate to the experimental method, using a solvent system compatible with solubility and downstream chemistry. Consider light exposure, repeated opening and solution stability when planning stock preparations. Store the unopened reagent at 2–8 °C and document lot information for traceability. For biotinylation workflows, select the correct activated biotin derivative separately when direct covalent labeling is required. Evaluate reagent grade and product specifications against the intended analytical or manufacturing procedure.
