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).

    Adsorption to aluminum oxide separated DSIP from tryptophan, which gives a method to monitor DSIP degradation.

    In plain wordsIn lab tests, a simple method separated DSIP from its breakdown product tryptophan, which helps study DSIP degradation.

    Summary
    Adsorption to aluminum oxide has been found to separate the two compounds and optimal conditions for the separation are described.
    1 context sentence
    Summary · context
    A major obstacle in monitoring degradation of DSIP has been the lack of an easy method to separate DSIP from tryptophan (Trp).

    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).
