to determine the molecular basis for changes in aromatase ( p450arom ) activity in rat ovarian follicles and corpora lutea , seven clones for rat p450arom cdna have been identified and isolated from a rat granulosa cell lambda gt11 cdna expression library using a 62 mer deoxyoligonucleotide probe ( derived from an amino acid sequence of purified human placental aromatase ) and a human placental p450arom cdna probe .
