What it is

DSIP was isolated from the blood of rabbits during electrically induced sleep and named for the delta waves it was linked to.

How each lot is tested

Samples from every lot go to an independent, ISO/IEC 17025 accredited lab. Its report covers three tests:

  • Purity by reversed-phase HPLC: the main peak's share of the total peak area.
  • Identity by mass spectrometry: the observed mass should match the expected 848.8 g/mol.
  • Endotoxin, measured for every lot.

The lot number on your vial is the number on its report. How to check a certificate of analysis walks through what to look for.

The amount on the label is the weight of the powder. Besides the peptide it includes counter-ions and some water; Purity vs. peptide content explains the difference.

Storage and handling

Store unopened vials at 2 to 8 °C, away from light, as printed on the label. Let a cold vial reach room temperature before you open it, so moisture doesn't condense on the powder. More bench habits are in Handling.
