  1. 01LabEx vivo tissueActivity measurement

    In lymphocytes from thymectomized guinea pigs, thymosin alpha‑1 at 10-1,000 ng/ml completely restored the ability to produce migration inhibition factor.

    In plain wordsIn guinea pig cells, thymosin alpha‑1 fully restored the cells' ability to make a signal molecule (MIF) that thymectomy had removed.

    Summary · context
    Thymosin fraction 5 restored the capacity of peripheral blood lymphocytes (PBL) from thymectomized adult guinea pigs sensitized with purified protein derivative (PPD) to produce migration inhibition factor (MIF) as measured in an agarose droplet microassay with peritoneal exudate cells.

    Thymosin alpha‑1 alone did not inhibit macrophage migration in the assay.
