Peptide Name
DSIP (Delta Sleep–Inducing Peptide)
Peptide Class
Synthetic neuropeptide; linear nonapeptide
Amino Acid Sequence
Trp–Ala–Gly–Gly–Asp–Ala–Ser–Gly–Glu
(WAGGDASGE)
Molecular Formula
C₃₈H₄₈N₁₀O₁₃
Molecular Weight
~848.9 g/mol
Peptide Type
Linear peptide; free N-terminus and C-terminal carboxylic acid
Chemical Structure
Linear nonapeptide composed exclusively of standard L-amino acids; no cyclization,glycosylation, or other post-translational modifications.
Solubility
Generally soluble in water and common aqueous laboratory buffers. Solubility may vary with pH, ionic strength, and peptide concentration.
Stability Characteristics
Lyophilized form: Store dry, protected from light and moisture, at −20 °C or below for long-term stability.
Reconstituted solutions: Prepare under sterile conditions; store in aliquots at cold temperatures and minimize repeated freeze–thaw cycles. Stability is buffer- and pH-dependent.
Source Classification
Synthetic (solid-phase peptide synthesis)
Purity Specification
≥98% (HPLC-verified)
Identity confirmed by mass spectrometry
Batch-specific Certificate of Analysis (COA) available
