we used a cloned human cdna probe homologous to the placenta chorionic gonadotropin beta subunit ( cgb ) and to the pituitary luteinizing hormone beta subunit ( lhb ) and southern blotting techniques to analyse dna from a series of rodent x human somatic cell hybrids for the presence of specific gonadotropin beta subunit related sequences .
