ETCTPSPKPLEGCTK

ETCTPSPKPLEGCTK is a 15-residue synthetic peptide with the sequence Glu-Thr-Cys-Thr-Pro-Ser-Pro-Lys-Pro-Leu-Glu-Gly-Cys-Thr-Lys. The sequence contains 2 cysteine residues, allowing thiol/disulfide chemistry when available. These sequence-derived properties describe the reagent chemically; no specific biological activity is assigned without product-specific experimental evidence.

• thiol-selective conjugation or immobilization studies
• 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.
