under conditions in which hcg-alpha combined with the hcg beta subunit ( hcg-beta ) to produce 95 % of the expected gonadotropin-binding activity in a rat testis radioreceptor-assay , a.l.-alpha incubation with hcg-beta resulted in only 2 % of the expected activity , and chago-alpha incubation with hcg-beta produced no detectable activity .
