Serum 17β-estradiol levels are similar between F2 and CRL animals. a An ELISA kit with a limit of detection of 1 pg/ml was used. Detection rates ranged from 0 to 0.6 in each group. No significant differences in detection rate were observed for F2 and CRL animals in each sex/age group. b Serum 17β-estradiol levels were highest in adult males, but were also variable. Significant differences in serum concentrations were not observed between F2 and CRL animals for any sex/age group. Sample sizes for ELISA were n = 6 F2 males, n = 5 CRL males, n = 6 F2 prepubertal females, n = 5 CRL prepubertal females, n = 6 F2 pubertal females, n = 5 CRL pubertal females
