Methods used to confirm identity, purity and lot consistency of Selank reference material.
Appearance
A Selank reference lot is typically a white to off-white lyophilized solid. Routine checks include inspecting appearance and confirming clean reconstitution in an appropriate analytical solvent, ensuring suitability for chromatographic and spectrometric measurement.
RP-HPLC purity
Reverse-phase HPLC provides the purity figure, generally not less than 98%. A water-and-organic gradient with an ion-pairing additive resolves the main peak from related impurities, and the integrated chromatogram supports the value on the certificate of analysis.
Mass-spectrometric identity
Identity is confirmed by mass spectrometry, matching the observed mass against the value near 751.9 g/mol expected for the peptide. The method can also surface common synthesis-related impurities such as oxidation or deletion sequences.
Lot control
Each lot is documented with analytical results so researchers can verify batch-to-batch consistency. Retaining this documentation with experimental records supports traceability and reproducibility for neuropeptide benchwork using the standard.
Evidence limits and research safety
Research findings can differ by model, assay, purity, formulation, and study design. Published cell, biochemical, and pre-clinical observations do not establish human or veterinary safety, efficacy, dosing, or suitability. Researchers should review the applicable SDS, institutional safety procedures, waste requirements, and lot-specific documentation before handling any reference material.
