PCR analyses of α-glycoprotein hormone subunit wild-type αSU (top) and null (bottom) alleles. The αSU wild-type allele results in a 0.22-kb product and the null allele results in a 1.1-kb product. Lanes, from left to right: wild type, p18-null, p27-null, αSU-null, p18/αSU double-null, p18HT/αSU-null, p18-null/αSU HT, and negative control.
