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, Thymulin (serum thymic factor) 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 Thymulin (serum thymic factor).

    Summary
    Looking for a "lymphocytic chalone" in Bovine spleen extracts, we isolated an immunosuppressive peptide, whose biochemical and biological properties are identical to those of the serum thymic factor FTS.

    In this study, Thymulin (serum thymic factor) 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 Thymulin (serum thymic factor).
