PT-141

PT-141 is a 8-residue synthetic peptide with the sequence Asp-His-Phe-Arg-Trp-Lys-Asp-Lys. phosphothreonine defines a threonine-phosphorylation state. The sequence contains 2 Lys and 1 Arg residues, contributing cationic character. These sequence-derived properties describe the reagent chemically; no specific receptor, enzyme, pathway, disease association, or biological activity is assigned without product-specific experimental evidence.

• phospho-specific antibody controls
• phosphoproteomics or kinase/phosphatase 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 experimental conditions.
