three members of a family of insulin-like growth factor binding proteins have been identified by nucleotide sequencing of cdna clones : the binding subunit of the 150 kda igf-binding protein complex in human serum , the 30 kda igf binding protein in human amniotic fluid , and a 30 kda binding protein ( bp-3a ) isolated from the rat brl-3a cell line .
