A new method for the purification of bioactive insulin-like growth factor-binding protein-3.

abstract：:A cDNA clone, lambda GTHP1del, encoding glutathione transferase (GST) P1-1, was isolated from a human K562 erythroleukemia cell line cDNA library. The coding sequence was lacking the codons for the N-terminal 34 amino acids. A DNA segment was designed in order to obtain the missing portion and a structure representing...
