DSIP Product Overview

Our DSIP research-grade synthetic nonapeptide, also known as delta sleep-inducing peptide or emideltide, is supplied for controlled scientific laboratory investigation, analytical method development, peptide characterisation, high-performance liquid chromatography assessment and mass-spectrometry workflows. The material comprises a defined linear sequence of nine amino-acid residues with free amino and carboxylic acid termini.

The material is handled with a focus on batch traceability, documented quality control and consistent laboratory presentation. Product identity, chromatographic purity, net peptide content, molecular form, amino-acid sequence, counter-ion content, water content, residual solvents, bacterial endotoxin results and other analytical specifications should be confirmed using the applicable batch Certificate of Analysis. Chromatographic purity should not automatically be interpreted as equivalent to the total net peptide content of the vial.

For the majority of routine analytical, investigative and general laboratory work, the Regular DSIP specification remains highly suitable. The premium black-and-gold ULTIMATE DSIP option provides an additional preparative high-performance liquid chromatography purification stage and a more stringent bacterial endotoxin and lipopolysaccharide testing specification for scientific projects requiring enhanced quality-control parameters.
