PubChem identifies Selank as H-Thr-Lys-Pro-Arg-Pro-Gly-Pro-OH and independently confirms the sequence, molecular formula, molecular weight, and CAS number.

Research Applications

Analytical characterization using HPLC, UPLC, and LC-MS workflows

Evaluation of heptapeptide identity and molecular integrity

Investigation of peptide-mediated molecular interactions under controlled in vitro conditions

Structure-activity analysis of tuftsin-related peptide sequences

Comparative assessment of Selank and structurally related research peptides

Peptide purity and molecular-weight confirmation

Evaluation of concentration-dependent molecular responses in defined assay systems

Comparative characterization of free-peptide and counterion-containing preparations

Stability profiling under controlled temperature, pH, buffer, and storage conditions

Quality Documentation

A batch-specific Certificate of Analysis and applicable analytical documentation should be available for each lot. Verify peptide identity, exact sequence, purity, molecular weight, formulation form, counterion content, and batch information against the records supplied with the individual product.

The formula and molecular weight listed above correspond to free Selank. Selank acetate is a chemically distinct counterion-containing preparation. PubChem and Cayman Chemical list Selank monoacetate separately as C₃₅H₆₁N₁₁O₁₁ with a molecular weight of approximately 811.9 g/mol and CAS 2703745-90-6.

Free Selank and Selank acetate should therefore not be treated as analytically identical materials. Batch-specific HPLC and mass-spectrometric documentation should be used as the final reference for product specifications.
