    Summary
    Des(1-3) IGF-I (13.3 nM), which has a reduced binding affinity for IGF-binding proteins (IGFBPs), administered with 11.1 mM glucose caused an immediate increase in insulin release, which fell to control values within 30 min.

    Summary · context
    Islets were isolated from adult male rats by collagenase digestion and Ficoll gradient separation, and were maintained in tissue culture for 48 h before perifusion.
    Summary · context
    Various doses (6.7-53 nM) of IGF-1, des(1-3) IGF-I or IGF-II were given either as a pulse between 30 and 35 min, or continuously from 30 to 90 min.
