Abstract

We investigated the bioactivities of the recombinant DNA-derived methionyl 20K hGH (20K-Met-hGH) and methionyl hGH (22K-Met-hGH). The growth-promoting activities in Nb2 cells of 20K-Met-hGH and 22K-Met-hGH were 10.7% and 93.5% of pituitary hGH (P-hGH), respectively. In the IM-9 lymphocyte assay, the binding activities of 20K-Met-hGH and 22K-Met-hGH to hGH receptor were 29.0% and 87.1% of P-hGH, respectively. Our data demonstrate that 20K-Met-hGH may have weaker biological potency than P-hGH.
