Mutants of human insulin-like growth factor II (IGF II) : expression and characterization of truncated IGF II and of two naturally occurring variants

Insulin-like growth factor II (IGF II) and four structural analogs, constructed by site-directed mutagenesis, were expressed as protein A fusion proteins in Escherichia coli BL21pLysS cells, cleaved with cyanogen bromide and purified by affinity chromatography and HPLC. Two mutants (Ser29 substitute...
