ABSTRACT:
The extracellular domain, or fragment thereof, of a gonadotropin glycoprotein hormone receptor is expressed and secreted in a soluble and functionally hormone-binding form. A recombinant baculovirus transfer vector is constructed to include a gene segment encoding the extracellular domain, or fragment thereof, of the glycoprotein hormone receptor joined in frame with a gene segment encoding a baculovirus signal peptide and operably linked to a baculovirus promoter. Recombinant baculovirus generated by transfection or co-transfection of insect cells are then used to infect insect host cells for the expression and secretion of soluble receptor.
