SARESTSDPKNEQF-Lys(Biotin)

SARESTSDPKNEQF-Lys(Biotin) is a 14-residue synthetic peptide with the sequence Ser-Ala-Arg-Glu-Ser-Thr-Ser-Asp-Pro-Lys-Asn-Glu-Gln-Phe. Biotin provides an affinity handle for streptavidin-based capture or detection. The sequence contains 1 Asp and 2 Glu residues, contributing anionic character near neutral pH. These sequence-derived properties describe the reagent chemically; no specific biological activity is assigned without product-specific experimental evidence.

• label-dependent capture or detection assay development
• LC-MS/HPLC analytical method development
• sequence-specific assay controls

Sequence-derived chemical properties support reagent selection and experimental planning but do not establish biological function. Solubility, aggregation, adsorption, conjugation efficiency, and assay performance should be validated under the intended conditions.
