Isolation, cloning and sequence analysis of the cDNA for the alpha-subunit of human chorionic gonadotropin

A 621-base pair fragment of the cDNA for the alpha-subunit of human chorionic gonadotropin has been isolated by cloning in a plasmid vector, and the complete nucleotide sequence determined. The entire coding region, including the 24-amino acid pre-sequence and most of the untranslated regions, are present in the fragment.
