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).

  1. 01LabNot a test of Delta sleep-inducing peptide (DSIP) aloneIn vitro (cell-free)Activity measurement

    A radioimmunoassay for DSIP measured DSIP-like material in body fluids with a minimum detectable concentration of 0.1 ng/ml.

    In plain wordsIn lab tests, a new assay could detect DSIP-like material in body fluids down to 0.1 ng/ml.

    Summary
    The assay allows measurement of DSIP-like material in body fluids with a minimum detectable concentration of 0.1 ng/ml standard DSIP (10 pg/tube).

    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).
