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

Abstract
A 621-base pair fragments of the c[complementary]DNA for the .alpha.-subunit of human chorionic gonadotropin was 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.
