Results from this study1

No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone1

In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Delta sleep-inducing peptide (DSIP).

    In a cell-free analytical method, HPLC with diode-array UV detection distinguished the Tyr1 analogue of delta-sleep-inducing peptide from the authentic peptide, which has tryptophan at the N-terminus.

    In plain wordsIn lab tests, a chemical analysis method told the DSIP Tyr1 analogue apart from the real peptide.

    Summary
    The Tyr1 analogue of delta-sleep-inducing peptide was easily distinguished from the authentic compound with a tryptophan at the N-terminus.

    In this study, Delta sleep-inducing peptide (DSIP) was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Delta sleep-inducing peptide (DSIP).
