Scientific Background | Biotin-KRKKFKIDDQRRTHNYDE is a 18-residue synthetic peptide with the sequence Lys-Arg-Lys-Lys-Phe-Lys-Ile-Asp-Asp-Gln-Arg-Arg-Thr-His-Asn-Tyr-Asp-Glu. Biotin provides an affinity handle for streptavidin-based capture or detection. The sequence is enriched in basic residues (4 Lys and 3 Arg), contributing cationic character under many aqueous conditions. No specific receptor, enzyme, pathway, disease association, or biological activity is assigned without product-specific experimental evidence. |
Experimental Notes | Sequence-derived chemical properties are provided to support reagent selection and experimental planning. They do not establish a biological function. Solubility, aggregation, adsorption, conjugation efficiency, and assay performance should be validated under the intended experimental conditions. |
