Purification and physiochemical properties of a recombinant bovine growth hormone produced by cultured murine fibroblasts.

abstract：:Kallikreins are a multigene subfamily of serine proteases that may have a role in processing precursors of polypeptide hormones and growth factors. The epidermal growth factor (EGF) immunoreactivity in mouse milk is derived from the membrane-bound EGF precursor located on the lumenal border of the alveolar cells in th...
