    2 context sentences
    Summary · context
    Purified IGF-1 and LR3 IGF-1 show bioactivity comparable to the standard IGF-1. • High heterologous expression of IGF-1 and LR3 IGF-1 is achieved by fermentation in a bioreactor.
    Summary · context
    Here, we report that human IGF-1 and its analog Long R3 IGF-1 (LR3 IGF-1) are recombinant expressed and produced in the Pichia pastoris (P. pastoris) expression system through being fused with highly expressed xylanase XynCDBFV.

Studies that did not test the peptide alone1

In this study, IGF-1 LR3 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 IGF-1 LR3.

  1. 02LabNot a test of IGF-1 LR3 aloneIn vitro (cells)Other

    In a 15-L bioreactor, fermentation of Pichia pastoris reached about 1 g/L of the XynCDBFV-TEV-LR3 IGF-1 fusion protein.

    In plain wordsIn a 15-L bioreactor, yeast produced about 1 g/L of a fusion protein that contains LR3 IGF-1.
