Lys(DSPE-PEG(2000))-TEELRVRLASHLRKLRKRLLR

Lys(DSPE-PEG(2000))-TEELRVRLASHLRKLRKRLLR is a 21-residue synthetic peptide with the sequence Thr-Glu-Glu-Leu-Arg-Val-Arg-Leu-Ala-Ser-His-Leu-Arg-Lys-Leu-Arg-Lys-Arg-Leu-Leu-Arg. DBCO provides a strained alkyne handle for copper-free click chemistry; An azide provides a bioorthogonal click-chemistry handle. The sequence contains 2 Lys and 6 Arg residues, contributing cationic character. These sequence-derived properties describe the reagent chemically; no specific biological activity is assigned without product-specific experimental evidence.

• 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.
